Answer:

V =108 ft^3

Step-by-step explanation:

The volume is found by

V = Bh where B is the area of the base

B = the area of the trapezoid

B = 1/2 (b1+b2)*h of the trapezoid

B = 1/2(4+6)*4 = 1/2(10)*4 = 20

Now we can find the volume

V = 20* 9

V =108 ft^3

A photocopy machine can print 735 copies in 7 minutes.what is the rate at which the machine prints the copies per minute

11111nata11111 [884]

The copy machine makes 105 copies per minutes.

Step-by-step explanation:

Given,

Copies printed by photocopy machine = 735

Time taken by machine = 7 minutes

To find the unit rate in terms of minutes, we will divide the copies printed by machine by the time taken.

Copies printed in one minute = $\frac{735}{7}$

Copies printed in one minute = 105 copies

The copy machine makes 105 copies per minutes.

What is the volume of a cone with a diameter of 30 feet and a hight of 60 feet

ivolga24 [154]

Answer:

4500 $\pi$ $ft^{3}$ or 4712.39 $ft^{3}$

What we need to know: The formula for the volume of a cone is: $V=\pi r^{2} \frac{h}{3}$

So we are solving for V

Step-by-step explanation:

1) Radius is half of diameter r=30/2 thus, your radius is 15

2) you then have all your variables so you can start plugging values into your equation:

r=15 h=60

$V=\pi 15^{2} \frac{60}{3} \\V=\pi (225)*(20)\\V=\pi(4500) \\V= 4500\pi$

This would be your exact answer but if you are solving for a rounded answer it would be

V~4712.39 $ft^{3}$
