Question

plz answer all questions friends fastly please ​

Answer 1

1)

Circumference=2πr

22=2*(22/7)*r

22*(7/22)=2r

7=2r

2r=7

r=7/2

r=3.5

Area=πr²=22/7*3.5*3.5=38.5

Area of semi circle=38.5/2=19.25

Rest of the questions will be solved in the same way. Only numbers will be changed..

Hope it helped you.
