Question

find the area and circumference of a circle of radius 28cm​

Answer 1

Answer:

circumference =2πr=2× 22/7×28=22×8=176 cm

Area =πr² = 22/7×28×28=88×28 =2464 cm²

Answer 2

Answer:

AREA = $\pi$$r^{2}$

$\frac{22}{7}$ * 28 * 28

22*4*28

88 * 28

2464 c$m^{2}$

_____________________________

CIRCUMFERENCE = 2$\pi$r

2* 22/7 * 28

44 * 4

176 c$m^{2}$
