Question

if the circumference of a circle is 88m, find the area of circle

Answer 1

2πr=88
r=88×1/2×7/22
r=14cm

area=πr^2=22/7×14×14= 616m^2

Answer 2

Given -

Circumference of circle is 88 m

To find -

The area of circle

Solution -

As we know that,

Circumference of circle = $2 \times \pi \times r$

Put the given values in these formula we get

$88 = 2\pi \times r$

$\frac{88}{2\pi} = r$

$\frac{44}{\pi} = r$

The value of π is 3.14 .

$\frac{44}{3.14} = r$

$r = 14.01$

So,

Radius (r) is 14.01 m.

Area of circle = $\pi {r}^{2}$

Put the value of r we get

Area of circle = $\pi \times {14.01}^{2}$

Square means multiply the given values with itself twice.

Square of 14.01 is 196.28

Area of circle = $\pi \times 196.28$

The value of π is 3.14.

Area of circle = $3.14 \times 196.28$

Area of circle = $616.31$

Hence,

Area of circle is 616.31${m}^{2}$
