Question

get the right pair of formulas
A
(a) the total surface area of hemisphere (solid)
(b) the volume of hemisphere
B
(1)
$\frac{2}{3} \pi \: r {}^{2}$
(2)
$3\pi \: r {}^{2}$
(3)2
$2\pi \: r {}^{2}$
​

Answer 1

Given :    Total Surface area of Hemisphere , Volume

To Find : Correct formulas

Solution:

volume of hemisphere  = (2/3) π r³

Total Surface area of Hemisphere  = 3πr²

Curved surface area of of Hemisphere  = 2πr²

volume of sphere  = (4/3) π r³

Total Surface area of  sphere  = 4πr²

Curved surface area of of  sphere  = 4πr²
