What is the volume of a cone with a height of 9.5 inches and a radius of 8 inches? Cone V = 1 3 Bh 1. Rewrite the formula for th

Nesterboy [21]

Answer:

636.4 in³

Step-by-step explanation:

Volume of a cone is given by:

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

where r is the radius of the base of the cone and h is its height.

It is given that, the radius of the base of the cone is, r = 8 in

The height of the cone is, h = 9.5

$\Rightarrow V = \frac{1}{3} \times 3.14 \times (8)^2 (9.5) = 636.4 in^3$

Thus, the volume of the cone is 636.4 in³

How to solve y for this problem:

True [87]

$16x+9=9y-2x\ \ |Add\ 2x\ to\ both\ sides\\\\
16x+9+2x=9y-2x+2x\\\\
18x+9=9y\ \ \ |Divide\ by\ 9\\\\
\frac{18x}{9}+\frac{9}{9}=\frac{9y}{9}\\\\
2x+1=y\\\\
Solution\ is\ y=2x+1.$
