Divide the circumference by 3.14 (pi): that gives you the diameter. Divide by 2: that gives you the radius. Square the radius, and multiply that by pi: that gives you the area.

## What would be the area of a circle whose circumference is 22cm?

In Si Units A Unit Of Charge Is Called A What Is The Role Of A Salt Bridge

## What is the area of circle whose circumference is 44 cm?

∴ Area of circle =154cm2.

## What is the radius of the circumference is 44?

r = 7cm is the answer.

## How much less is the area of a square whose perimeter is 44 cm than the area of a circle whose circumference is 44 cm?

The area of a square whose perimeter is 44 cm is 33 sq.cm. less than the area of a circle whose circumference is 44cm​ Difference in area = 154 – 121 = 33 sq.cm.

## How many circles of radius 2 cm will have the same area as the square of side 44 cm?

## What is the area of the circle the circumference of which is equal to the perimeter of a square of side 11 Centimetre?

Areas Related to Circles What is the area of the circle, the circumference of which is equal to the perimeter of a square of side 11 cm. = 4 x 11 = 44 cm.

## Which has greater area a square of perimeter 44cm or a circle having circumference 44 cm?

Which has greater area, a square of perimeter 44 cm or a circle having circumference 44 cm. side of square-44/4=11cm and area =m^2 AND r of circle=44×7/(22×2)=7cm and area=22×7×7/7=154cm^2 That’s why cicle’s area is more.

## Which has greater area square or circle?

The area of a circle is πr2 , where r is the radius of the circle. The area of a square is s2 , where s is the side length. But s = P/4, so the area of a square is P2 /16. Since 1/(4π) > (1/16), the circle has more area than the square.

## What is the ratio of the circumference of the circle to the perimeter of the square?

Perimeter of square is half the circumference and hence is π×r , where π=3.1416 .

## Which of the following is the circumference of circle?

the formula for circumference of a circle is 2 x pi x r(radius).

## What is the ratio of the areas of a circle and an equilateral triangle?

The Ratio of the Areas of circle and equilateral ∆ is π : √3 .

## What is the ratio of the area of the circle?

So the area of the circle is πr2=10×2π. So the ratio of the area of the circle to the area of the square is 10×2π:36×2, which is equivalent to 5π:18, as required.

## What is the ratio of triangles to circle?

Answer. Ratio of areas of triangles = 6nr : 3nr 2 = 4:1. 2. h is the radius of the inscribed circle.

90°

## How do you prove angles at the center theorem?

Theorem: Angle at the centre of a circle is twice the size of the angle at the circumference. If an arc subtends an angle at the centre of a circle and at the circumference, then the angle at the centre is twice the size of the angle at the circumference.

## What is a subtended angle at the circumference?

Angle at the Circumference If the end points of an arc are joined to a third point on the circumference of a circle, then an angle is formed. For example, the minor arc AB subtends an angle of 45º at C. The angle ACB is said to be the angle subtended by the minor arc AB (or simply arc AB) at C.

## What is meant by Subtended angle?

1. geometry. to be opposite to and delimit (an angle or side) 2. (of a bract, stem, etc) to have (a bud or similar part) growing in its axil.

## What is meant by Subtend?

1a : to be opposite to and extend from one side to the other of a hypotenuse subtends a right angle. b : to fix the angular extent of with respect to a fixed point or object taken as the vertex a central angle subtended by an arc the angle subtended at the eye by an object of given width and a fixed distance away.

## What does Subtend mean in maths?

To take up the side opposite an angle or arc.
