Question

Find the diameter of a wheel whose
circumference is 264 cm.

Answer 1

Answer:

Step-by-step explanation:

Circumference = 2 π r

264 = 2 x 22/7 x r

264 x 7/ 44 = r

r = 42

∴ d = 84

Answer 2

circumference of circle =
$2\pi \: r = 264$
2×22/7×r= 264

44/7×r = 264

r= 264×7/44

r = 42cm

then diameter = 2r

2×r
2×42= 84cm ans
