Question

If radius is 7cm find the diameter and circumference

Answer 1

Diameter = 2X radius
So diameter =2 X 7 cm
Diameter = 14cm
Circumference of circle = 2πr(r=radius of circle)
Circumference of circle= 44/7X 7
= 44cm

Answer 2

$\large\pink{\boxed{Solution :}}$

$\large\blue{\boxed{Given}}$

$Radius = 7cm$

$\large\blue{\boxed{Diameter = 2 \times Radius }}\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 2 \times 7cm \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 14 \: cm$

$\large\blue{\boxed{Circumference = 2\pi \: r}} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = (2 \times \frac{22}{7} \times 14) \: cm \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 88 \: cm \: \: \large\green{\boxed{ Ans}}$
