Question

find the area of a circle if its circumference is 88cm​

Answer 1

Answer: 616 cm²

Step-by-step explanation:

circumference = 88cm

= 2∧r = 88

= r = 88/2∧

= r = 44/22 * 7

= r = 2*7

= r = 14 cm

area = ∧r²

= 22/7 * 14*14

= 616 cm²

Answer 2

Given,

The circumference of circle =88cm

To find= Area of Circle

ANSWER

Now, Circumference of a circle = 2πr

=>2πr = 88

=>πr =$\dfrac{88}{2}$

=> πr = 44

=>r =$\dfrac{44}{\pi}$

=>r =$\dfrac{44\times 7}{22}$

=>r = 2×7

=>r = 14cm.

Now, we know that=>

Area if circle = πr^2

=>Area of circle

=>$\dfrac{22\times14\times14}{7}$

=> Area of circle = 616cm^2.

Hence the area of the circle will be 616cm^2.

Remember

Area of circle = πr ^2

Circumference of circle = 2$\pi$ r
