Answer:

900 cubic inches.

Step-by-step explanation:

Given the following data;

Volume of right circular cone = 300in³

We know that the volume of a right circular cone is given by the formula;

$V = \frac {1}{3} \pi r^{2}h$

Where;

V is the volume of right circular cone.

r is the radius of the base of the right circular cone.

h is the height of the right circular cone.

The volume of a right circular cylinder is given by the formula;

$V = \pi r^{2}h$

Thus, multiplying the volume of the right circular cone by 3 would give us the volume of the right circular cylinder.

$V = \frac {1}{3} \pi r^{2}h * 3$

Substituting into the equation, we have;

$V = 300 * 3$

V = 900in³

Therefore, the volume of a right cylinder that has the same base and height as the cone is 900 cubic inches.

If AB = BC = CA, what is m1?

Alborosie

Answer:

60°

Step-by-step explanation:

All the side lengths of the triangle have the same measurement. This makes it an equilateral triangle. By the definition of an equilateral triangle, all the angles are congruent, therefore all their measurements are the same. There are 3 total angles in a triangle, and the total sum of the angel measurements of a triangle is 180. Divide 180 with 3:

180/3 = 60

60° is your answer.
