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.

What is the area of major sector DFE?

melomori [17]

Answer:

B. 171.74 cm²

Step-by-step explanation:

Area of a sector = $\frac{\theta}{360} \times \pi r^2$ .

Where,

$\theta = 260$

radius (r) = 8.7 cm

Plug in the values into the formula

Area of sector = $\frac{260}{360} \times \pi 8.7^2$

Area of sector = $\frac{260 \times \pi 75.69}{360}$

Area of sector = 171.74 cm² (approximated)
