Question

if circumference=72.6 cm so what is the radius and diameter answer with method

Answer 1

Answer:2pie r = 72.6

2×22/7×r = 72.6

r = 72.6×7/44

r = 11.55

d = 2 r

d = 2× 11.55

d = 23.1

Step-by-step explanation:

Answer 2

Answer:

now , c = 2π r

= 72 . 6 = 2 × 22/7 × r

= r = 72.6 × 1/2 × 7/22

= r =11.55

so ,radius =11.55cm

diameter, d = 2r = 2 × 11.55=23.7cm
