Question

Find The Radius Of a circle whose circumference is 5.28m​

Answer 1

$2\pi \: \times r$

$\pi = \frac{22}{7}$

$2 \times \frac{22}{7} \times r = 5.28$

$\frac{44}{7} = 5.28 \times \frac{7}{22}$

r = 21/25

So raidus is 21/25

Hope it helps to u ✌️✌️

Answer 2

Answer:

Radius is 84 cm.

$2\pi \: r \: = circumference \\ 2 \times \frac{22}{7} \times r = 5.28 \\ r = 5.28 \times \frac{1}{2} \times \frac{7}{22.} \\ r = 0.84 \: m \\ r \: = 84 \: cm$
