Question

A hemispherical bowl is made of brass has an inner diameter 35 cm. What is the inner surface area? URGENT

Answer 1

Answer:

The inner surface area of a hemispherical bowl will be: 1923.25 cm²

Step-by-step explanation:

Given

d = 35 cm

as

$r=\frac{d}{2}$

  $=\frac{35}{2}$

   $= 17.5$ cm

The inner surface area of a hemispherical bowl = 2πr²

$=2\times 3.14\times \left(17.5\right)^2$

$=6.28\:\times \:17.5^2$

$=1923.25$

Hence, the inner surface area of a hemispherical bowl will be: 1923.25 cm²
