## Answers ( )

Answer with Step-by-step explanation:We are given that

a.

b.Radius=2.58 cm

Substitute the values in the formula and

Hence, the area of circle =

20.9 square cmc.Area of circle=1530 square cm

Hence, the radius of circle=22.07 cmc.Area of circle of radius 15.2 cm=

Area of circle of radius 15.1 cm=

Hence, the area of circle whose radius is 15.2 cm is greater than the area of circle of radius 15.1 cm by 9.52 square cm .
