A ladder leaning against a building makes an angle of 65 degrees with the ground and reaches a point on the building 20 feet abo
lesya692 [45]
22 feet. Using the sine rule theory: 20/sin(65)=x/sin(90). You know that it's 90 degrees because you assume the ground and the building make a 90 degree angle. So, you cross multiply and get 20sin(90)/xsin(65) and solve for x.

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.
