Question

Find the volume of the specified cone. Use 3.14, and round your answer to the nearest whole number.

Answer 1

Answer: 59 cubic cm.

Step-by-step explanation:

The volume of cone is given by :-

$V=\dfrac{1}{3}\pi r^2 h$, where r is radius and h is height of the cone.

Given: Diameter : 5 cm

Then Radius =$\dfrac{5}{2}=2.5\ cm$

Height : 9 cm

Then , the volume of the cone will be :-

$V=\dfrac{1}{3}(3.14) (2.5)^2 (9)=58.875\approx59\text{ cm}^3$

Hence, the volume of the cone = 59 cubic cm.

Answer 2

The formula for the volume of a cone is V=(1/3)πr^2h.
To find r (radius) divide the diameter by 2, giving you 2.5 cm.
Plug in the numbers now !
V=(1/3)(3.14)(2.5^2)(9)
V=(1/3)(3.14)(6.25)(9)
V=(1/3)(176.625)
V=58.875
Therefore, the volume of the cone is about 59cm^3 :)
