Question

Area of circumference of a circle whose circumference is 88cm

Answer 1

Circumference of circle =88

2nr = 88
nr =44
r= 44*7_22
R = 14
area = nr2
= 22_7*14*14
= 28*22
= 616

Answer 2

Answer:

Area of circle is 616.32 ${cm}^{2}$

Step-by-step explanation:

Given -

Circumference of circle is 88 cm

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 cm.

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 = $616.32$

Hence,

Area of circle is 616.32 ${cm}^{2}$
