Raymond built a “rocket" made from a cylinder and a cone. He filled the rocket
lianna [129]

Answer:

Rocket can hold maximum 4.5 gallons of water.

Step-by-step explanation:

Volume of the rocket = Volume of the cone on the top + Volume of the cylinder at the bottom

Volume of the cone = \frac{1}{3}\pi r^{2}h

Here r = radius of the circular base

h = height of the cone

Volume = \frac{1}{3}\pi (4)^{2}(14)

             = \frac{224\pi }{3} cubic inch

Volume of the cylinder = \pi r^{2}h

Here r = radius of the base

h = height of the cylinder

Volume = \pi (4)^{2}(16)

             = 256π cubic inches

Volume of the rocket = \frac{224\pi }{3}+256\pi

                                   = \frac{992\pi }{3}

                                   = 1038.82 cubic inches

Since 231 cubic inches volume of a rocket can hold water = 1 gallon

Therefore, 1038.82 cubic inches space can hold water

= \frac{1038.82}{231}

= 4.497

≈ 4.5 gallons

Rocket can hold 4.5 gallons of water.

Martina walked 3/4 of a mile in 1/5 of an hour. At this rate , how far can Martina walk in one hour?
Lapatulllka [165]
Hey there!


To make this easier, we need to transform the numbers in decimal

3/4 = 0.75

1/5 = 0.2

So Martina walks 0.75 miles in 0.2 hour. They want us to find how far will she wake in 1 hour.

So we say:

0.75......>0.2 hr
x...........1 hr

Cross multiply

0.2 * x = 1 * 0.75

0.2x = 0.75

x = 0.75/0.2

x = 3.75

Martina will work 3.75 miles in one hour.

I hope this helps!
