Hello!

Let's write some information contained in the exercise:

• radius,: 1.5in

,

• pi,: 3.14

In this exercise, we have a hemisphere (half of a sphere). So, we can solve it using the formula of the volume of the sphere, then we'll divide the obtained result by 2, look:


V_(\circ)=(4\cdot\pi\cdot r^3)/(3)

Let's replace it with the values:


V_{\operatorname{\circ}}=(4\cdot3.14\cdot1.5^3)/(3)=\frac{12.56\operatorname{\cdot}3.375}{3}=(42.39)/(3)=14.13in^3

As we are working with a hemisphere, we have to divide it by 2:


V=(14.13)/(2)=7.065in^3

Right Answer:

Third alternative.
