Find the volume of a cone with a height of 11 cm and a base radius of 6 cm. Use the value 3.14 for n, and do not do rounding. Be
mrs_skeptik [129]

Given:

The cone with radius 6 cm and height 11cm.

Required:

Find the volume of a cone.

Explanation:

The formula for volume of cone:

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

We have radius = 6 cm and height = 11 cm.

So,

\begin{gathered} V=\frac{1}{3}\times3.14\times6^2\times11 \\ V=414.48cm^3 \end{gathered}

Answer:

Volume of cone equals 414.48 cm cube.

A population of caribou in a forest grows at a rate of 3% every year. If there are currently 208 caribou, which function represe
svet-max [94.6K]

Answer:

f(x)=208^0.3x

Step-by-step explanation:

Think of this as a graph. You start out with 208 caribou, which is your y intercept, as it is there when the growth is 0.

The generic formula fr an exponential equation is a^x.

A represents your initial value. In this case, its 208

x represents the growth. In this case, it's 0.3%.

Your equation should be f(x)=208^0.3x

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 18 cm
Naily [24]

Answer:

12 cm³

Step-by-step explanation:

the volume of the sphere = 4/3 πr³

the volume of the cylinder (h=2r)= πr².2r

= 2πr³

the volume ratio of S : C =

4/3 πr³ : 2 πr³

= 4/3 : 2

= 4 : 6

= 2 : 3

so, the volume of the Sphere =

2/3 × 18 = 12 cm³
