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

The inner surface area is: 1923.25 cm²

Step-by-step explanation:

A hemispherical bowl is made of brass has an inner diameter of 35 cm.

i.e. d = 35 cm

As the radius is basically half of the diameter.

r = d/2

  = 35/2

   = 17.5 cm

The inner surface area of a hemispherical bowl = 2πr²

= 2(3.14)(17.5)²

=1923.25 cm²

Therefore, the inner surface area is: 1923.25 cm²

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

so, converting firstly the mixed fractions to improper fractions and then "adding".
