Question

$\sqrt[ { { {? \times \frac{?}{?} \times \frac{?}{?} }^{?} }^{?} }^{?} \times \frac{?}{?} \times \frac{?}{?} ]{?}$
​

Answer 1

Explanation:

increase in radius = (1.02 - 1.00)/ 1.00 x 100 = 2%

then increase in volume = 4 /3 π 3 x ∆ r / r x 100

= 4 π x 2%

= 8π /100

option 3. is the answet
