Question

circle A has a radius of 21 meter circle b has a radius of 28 meters find the circumference of each circle in term of N

Answer 1

Circle A = 132

Circle B = 176

Explanation:

`C=2\pi R`

`C=2\pi (21)`

`2 x \pi =6.2831`

6.281 x 21 = 131.94

Circle A = 132

6.2831 x 28 = 175.92

Circle B = 176

Answer 2

The circumference of each circle is 42π and 56π

How to find the circumference of each circle

From the question, we have the following parameters that can be used in our computation:

• Circle A has a radius of 21 meter
• Circle b has a radius of 28 meters

The circumference of each circle can be calculated using

C = 2πr

Substitute the known values into the equation

C(A) = 2π * 21

C(B) = 2π * 28

Evaluate

C(A) = 42π

C(B) = 56π

Hence, the circumference of each circle is 42π and 56π
