4 0

Answer:

b = 15.7 -2a

Step-by-step explanation:

You are asking us to solve for b

2a +b = 15.7

Subtract 2a from each side

2a-2a+b = 15.7 -2a

b = 15.7 -2a

A right circular cone has a radius of 6 inches and a volume of 180 cubic inches. What is the height of the cone? A. 5 in. B. 15
dlinn [17]

Answer:

A. 5 in.

Step-by-step explanation:

The formula for the volume of a cone is :

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

so

180 in.^{3} = \pi * 6^{2}* \frac{h}{3}

180 in.^{3} = 3.14* 36* \frac{h}{3} \\180 in.^{3} = 113.04 * \frac{h}{3}\\3 * 180 in.^{3} = 113.04 * \frac{h}{3} * 3 \\\\\\\

540 / 113.04 = 113.04 h /113.04\\h = 4.8 in

When you round you get

h= a. 5 in.

Length = 31 ft
width = 19 ft


Assume that the width of the rectangle is w.
We are given that the length is 12 ft more than the width. This means that the length of the rectangle is w + 12

The perimeter of the rectangle in this case would be:
perimeter = 2 (length + width)
perimeter = 2 (12 + w + w)
perimeter = 24 + 4w

Assume that Dan would use all 100 ft of fencing to surround the yard. This would mean that the largest perimeter is 100 ft.

Therefore:
perimeter = 24 + 4w
100 = 24 + 4w
4w = 100 - 24
4w = 76
w = 19 ft

Since we have calculated that the width of the yard is 19 ft, we can substitute to get the length as follows:
length = 12 + w
length = 12 + 19
length = 31 ft
