Question

3. Find the radius of a circle whose circumference is 176 cm​

Answer 1

Answer:

r = 28.01

Step-by-step explanation:

C (circumference) = 176

using the formula:

C = 2π r

solving for r :

r = C/2π

= 176/2.π

= 28.01127

Answer 2

Answer:

radius = 28 cm

Step-by-step explanation:

circumference = 2πr

so, 176 = 2*22/7*r

r = 176*7/44

r = 4*7

r = 28 cm
