Question

find the circumference diameter = 28 cm find the radius circumference= 220 cm find the area radius = 56 cm​

Answer 1

d = 28 r = d/2

C = 2 pie r

2 * 3.14 * 28/2

2 * 3.14 * 14

87.92 cm

C = 220

r = C/(2 * pie)

220 / 2 * 3.14

35 cm

r = 56

A = pie r²

3.14 * (56)²

3.14 * 3136

9,847.04 cm²
