Abigail is participating in a science fair where she has to create a model of a volcano. She decides to make the volcano in the shape of a cone. If the volume of the cone-shaped volcano model is the same as the options given below, which one should she choose?

Question

A) 150.72 cm
B) 151cm
C) 452.16
D) 75.36

Answer 1

To calculate the volume of a cone, you can use the formula V = (1/3)πr^2h, where r is the radius of the base and h is the height of the cone.

Since the question states that the volume of the volcano model is the same as one of the given options, we can calculate the volume using the formula for each option and see which one gives the same result.

Let's assume the radius of the base is r and the height of the cone is h.

For option A) 150.72 cm:
V = (1/3)πr^2h = (1/3)π(r)(15.36) = 5.12πr

For option B) 151 cm:
V = (1/3)πr^2h = (1/3)π(r)(15.1) = 5.03πr

For option C) 452.16 cm:
V = (1/3)πr^2h = (1/3)π(r)(136) = 45.33πr

For option D) 75.36 cm:
V = (1/3)πr^2h = (1/3)π(r)(18.72) = 6.24πr

Comparing the calculated volumes, none of the options match exactly with the given volume. Therefore, none of the options are correct.
