A cylinder and a cone have the same volume. The cylinder has a radius of 2 inches and a height of 3 inches. The cone has a radiu

jolli1 [7]

ANSWER

$h= 4in.$

EXPLANATION

The volume of a cylinder is calculated using the formula;

$v = \pi \: {r}^{2} h$

It was given that, the cylinder has a radius of 2 inches and a height of 3 inches.

This implies that,

$v = \pi \times {2}^{2} \times 3$

$v =12 \pi$

The volume of a cone is given by

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

The cone has a radius of 3 inches:

$v=\frac{1}{3} \times \pi \times {3}^{2} h$

$v=3 \pi h$

The two volumes are the same:

This implies that,

$3 \pi h = 12\pi$

Divide both sides by 3π

$h= 4in$

Use the following data set to complete the problems.

Yuri [45]

Answer:

The interval 44-47 has a frequency of 3 .

The interval 48-51 has a frequency of 4.

The interval 56-59 has a frequency of 1.

The given data set is:

42, 43, 46, 47, 47, 48, 49, 50, 51, 53, 55, 55, 59

The number lying in the interval 44-47 are :46, 47, 47

So the interval 44-47 has a frequency of 3.

The number lying in the interval 48-51 are :48, 49, 50, 51

So, the interval 48-51 has a frequency of 4.

The number lying in the interval 56-59 is: 59

So, the interval 56-59 has a frequency of 1.
