The volume of a cone is 20pi cubic meters. What is the volume of a cylinder with the same base and height?

Recall, the volume of a cone is 1/3pi times radius of base times height.
V cone_{} =  \frac{1}{3} * \pi *r^2*h

Volume of a cylinder is the same but without the 1/3
V cyl_{} = \pi*r^2*h

It gives you the cone volume 20pi and that the radius and height of both of them are the same values.
20 \pi= \frac{1}{3}  \pi r^2h
V cyl_{}= \pi r^2h

since it says the radius and height are the same for both , you can equate the two, you can solve both equations for r^2*h and then equate what is on the other side.
60=r^2h

\frac{V}{ \pi } =r^2h

so
60= \frac{V}{ \pi }
V=60  \pi

At track practice,Sheila worked on the long jump. Her first jump measured 3 yards, 2 feet, 8 inches. Her second jump measured 2
jolli1 [7]
The length is 19.5 feet. this is because when you add the yards, it equals 15 feet. Next, add 1 + 2 feet from the first and second jump. 10+8 inches equal 1.5 feet. Next, add 15 feet+3 feet+1.5 feet to get 19.5 feet.
