Question

someone plz answer
plz.. plz.. plz..

Answer 1

Area = π r²
308 = π r²
r = √{308/π}
= √{ 308 × 7 / 22 }
= √ {14 × 7 }
= 7 √2
One side of rectangle has side length = r
Other side length = 2r
Perimeter = 2(r+2r)
= 6r
= 48√2
Hope it may help you !!!!!

Answer 2

area of 1 st circle= 308/2
=154cm cube
by pie r square, 22/7×rsquare =154
by this r = 7
so length of rectangle= 7×4 =28
and breadth =7×2=14
perimeter = 2(14+28)
42×2=84cm
