Start with a proportion, to get the number of degrees in 30 seconds:
(150 degrees / 5 seconds) = ('D' degrees / 30 seconds) .
Cross multiply the proportion: (150 x 30) = 5 x D
4,500 = 5 x D
Divide each side by 5 : 900 = D
The globe turns 900 degrees in 30 seconds.
How many rotations is that ?
Each rotation is 360 degrees.
So 900 degrees is
(900 / 360) = <em>2.5 rotations</em> in 30 seconds.
-19x-11 should be the answer... if the 19 and x aren’t combined then the answer is x-30

The solid shape is a cone and a half sphere. So the equation would be (cone volume) + (1/2 sphere volume):
If the volume of the cone is 270pi and the height of the cone is 10, then:
The radius of the object is 9 cm. Therefore, we can plug into the formula for the total volume:
The total volume is 513 pi cm^3
