Question

1. Find the circumference and area of
circle with radius 5 cm.

Answer 1

3l.42cm

Explanation:

C =2(3.14) × 5cm

C= 31.42cm

Area = pie r2

area =3.14 × 5cm ×5cm

area= 78.5cm

Answer 2

Hey There!

Let's solve...

First let's find out circumference

We know the formula is

`2 \pi r \\ \\ = 2 * 5 * 3.14cm \\ \\ = 10 * 3.14cm \\ \\ = 31.4cm`

Now let's find out area...

The formula is

`\pi r^(2) \\ = 3.14 * {5}^(2) \\ = 3.14 * 25 \\ = 78.50 {cm}^(2)`

I hope it is helpful to you...

Cheers!_____________
