Find the volume of a right circular cone that has a height of 10.7 in and a base with a diameter of 8.1 in. Round your answer to

scoundrel [369]

Answer:

$V = \pi r^2 h$

And for this case the value for the height is $h = 10.7 in$ the diameter is provided $D = 2r = 8.1 in$ so then the radius is given by:

$r = \frac{D}{2}=\frac{8.1 in}{2}= 4.05 in$

Then we can find the volume with the first formula and replacing we got:

$V = \pi (4.05in)^2 (10.7 in)= 551.4 in ^3$

The final answer for this case would be 551.4 cubic inches

Step-by-step explanation:

The volume for a right circular cone is given by this formula:

ayme built a box in the shape of a rectangular prism with the dimensions shown. What is the volume of the box, in cubic inches?

Snezhnost [94]

Answer:

$64(in)^{3}$

Step-by-step explanation:

The volume of a box is equal to the length l times the width w times the height h.

$(lenght) \times (width) \times (height)$

Substitute the values of the length l=8, the width w=2, and the height h=4 into the formula.

$8 \times 2 \times 4$

Multiply 8 by 2.

$16 \times 4$

Multiply 16 by 4.

$64 {in}^{3}$

Hence, the volume of the rectangle prism is 64(in)³.
