Answer 1

Answer:1897.28

Step-by-step explanation:

Answer 2

As we know that there is a formula to find circumfrence of a Circle.

Area of circle = 301. 84 cm²

πr² = 301.84 cm²

22/7 x r² = 301.84

r² = 301.84 x 7/22

r² = 96.04

r = √96.04

r = 9.8 cm

Circumference = 2πr

C = 2 x 22/7 x 9.8

C = 61.6 cm
