Answer 1

Let $r_{a}$, $r_{b}$ be radius of A & B respectively

Given S.A of B is 300% greater then S.A of A

4$\pi r$$\frac{2}{b}$ = 4 x 4$\pi r \frac{2}{a}$

$r_{b}$ = $2r_{a}$

Volume of A ($v_{a}$) = $\frac{4}{3}$$\pi r\frac{3}{a}$

Volume of B ($v_{b}$) = $\frac{4}{3} \pi (rb)^{2} = \frac{4}{3} \pi (2r_{a} )^{3}$ = 8 x $\frac{4}{3} \pi \frac{3}{a}$

$v_{b} = 8v_{a}$

∴ Volume of A is 87.5% lower than B
