Question

Find the radius of a circle whose circumfrence is 5.28cm

Answer 1

Answer:

0.84 cm

Step-by-step explanation:

2 * pi* R = 5.28

2* (22/7)* R = 5.28

R = 0.84 cm

Answer 2

Answer:

Circumference = 2πr

Radius = ?

$5.28 = 2\pi r$

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

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

$r = 0.84$

Hence , Radius of the circle is 0.84 cm
