Answer:

1. V = 94 meters cubed

2. V = 8 feet cubed

3. V = 57 inches cubed

Step-by-step explanation:

The volume of a cone is 1/3 the volume of a cylinder. So all you need to do is plug the numbers into the formula for the volume of a cylinder and then you have the answer.

The formula for a cylinder is V= (3.14 or pi) * radius squared * height

The formula for a cone is V= (3.14 or pi) * radius squared * height * 1/3

So here you go.....

1. V= 3.14 x 9 x 10 x 1/3 V = 94 meters cubed

2. V= 3.14 x 4 x 2 x 1/3 V = 8 feet cubed

3. V = 3.14 x 9 x 6 x 1/3 V = 57 inches cubed

Please give me brainiest!

Petra was given 12 yards of fabric to make costumes for the school play if each costume requires 1 1/2 yards how many costumes c

solmaris [256]

Petra can make 8 costumes with 12 yards of fabric

<h3><u>Solution:</u></h3>

Given that Petra was given 12 yards of fabric to make costumes for the school play

Each costume requires $1\frac{1}{2}$ yards

<em><u>To find: number of costume Petra can make</u></em>

The number of costume Petra can make is calculated by dividing the total fabric she has by fabric needed for one costume

$\text {number of costume Petra can make }=\frac{\text {total fabric she has }}{\text {fabric needed for one costume }}$

Total fabric she has = 12 yards

Fabric needed for 1 costume = $1\frac{1}{2} = \frac{2 \times 1 + 1}{2} = \frac{3}{2}$ yards

Therefore,

$\text {number of costume Petra can make }=\frac{12}{3 / 2}=\frac{12}{3} \times 2=8$

Thus petra can make 8 costumes with 12 yards of fabric

A fencing company charges $22per foot to install a wood fence around a rectangular pool area that is 20 feet wide and 38 feet lo

pantera1 [17]

We will need to find the perimeter here, since in this context we’re talking about fencing around a rectangular pool. The formula for perimeter is P = 2L + 2W. The L and W can stand for length/width which is the same as wide/long in this problem. I will now plug in the numbers. P = 2(38) + 2(20) which gives us 76 + 40. 76 + 40 is 116. Therefore, the perimeter is 116 ft.

I know that the fencing company charges $22 per foot. I can multiply 116 x 22 to give me $2552. The answer is $2552.
