Question

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

Answer 1

Answer:

3l.42cm

Step-by-step explanation:

C =2(3.14) × 5cm

C= 31.42cm

Area = pie r2

area =3.14 × 5cm ×5cm

area= 78.5cm

Answer 2

Answer:

Hey There!

Let's solve...

First let's find out circumference

We know the formula is

$2 \pi r \\ \\ = 2 \times 5 \times 3.14cm \\ \\ = 10 \times 3.14cm \\ \\ = 31.4cm$

Now let's find out area...

The formula is

$\pi r^{2} \\ = 3.14 \times {5}^{2} \\ = 3.14 \times 25 \\ = 78.50 {cm}^{2}$

I hope it is helpful to you...

Cheers!_____________
