Multiple choice

A hemispherical bowl has internal radius of $3 cm$ then the capacity of the bowl is c.c. is

  1. $\displaystyle 21 \pi$
  2. $\displaystyle 18 \pi$
  3. $\displaystyle 15 \pi$
  4. $\displaystyle 24 \pi$

B Correct answer
Explanation

The interest earned on the loan is (36% - 24%) of 5500 for 2 years. 12% of 5500 is 660. For 2 years, 660 * 2 = 1320.

AI explanation

The capacity of the bowl is its volume, found using the formula for the volume of a hemisphere, two thirds times pi times the radius cubed. Substituting the radius 3 cm gives two thirds times pi times 3 cubed, which simplifies to 18 pi cubic centimeters.
