Answer:
V = 42.41cm^3
Explanation:
In order to calculate the volume of the solid, you use the following formula:
[tex]V=\frac{1}{3}\pi r^2 h[/tex]
where
r: radius of the circular base of the cone = 3 cm
h: height from the circular base to the peak of the cone = 4.5 cm
You replace the values of r and h in the formula for the volume V:
[tex]V=\frac{1}{3}\pi(3cm)^2(4.5)=42.411cm^3\approx42.41cm^3[/tex]
hence, the volume of the solid is 42.41 cm^3
