Question

A circle has an area of 2464 sq. cm. Find its circumference (in cm)

Answer 1

Answer:

Hey there!

Given, Area of circle = 2464 sqrt.cms

We know that,

Area of circle = πr² .

We will first find out radius and then find circumference.

So,

➜πr²= 2464

➜ r² = 2464 * 7/22

➜r² = 784

➜ r = 28 cm

Now, circumference of the circle = 2πr = 2 (22/7)(28) = 2(22)(4) = 88(2) = 176cm .

Therefore, The circumference of the circle is 176 cms

Answer 2

GIVEN:

Area of a cricle = 2464cm²

TO FIND:

Circumference of the circle

SOLUTION:

To find the circumference of circle, we should find the radius of circle first.

We know that,

Area of a circle = πr²

==> πr² = 2464

==> 22/7 × r² = 2464

==> r² = 2464 × 7/22

==> r² = 112 × 7

==> r² = 784

==> r = √784

==> r = 28cm

Radius of the circle = 28cm

Circumference of circle = 2πr

= 2 × 22/7 × 28

= 44 × 4

= 176cm

Therefore, the circumference of circle is 176cm.
