A sphere and a cylinder have the same radius and height. The volume of the cylinder is 18 cm3
Minchanka [31]

Answer:

12 cm³

Step-by-step explanation:

Let's say the radius of the sphere and cylinder is r and the height is h. However, notice that the "height" of the sphere is the same thing as the diameter, which is 2r, so h = 2r.

The volume of a sphere is denoted by: V=\frac{4}{3} \pi r^3 , where r is the radius.

The volume of a cylinder is denoted by: V=\pi r^2h, where r is the radius and h is the height. Plug in 2r for h and 18 for V:

V=\pi r^2h

18=\pi r^2*2r=2\pi r^3

\pi r^3=18/2=9

Now plug in 9 for πr³ in the volume formula for the sphere:

V=\frac{4}{3} \pi r^3

V=\frac{4}{3} *9=12

The volume of the sphere is 12 cm³.

The graph of f ′ (x), the derivative of f of x, is continuous for all x and consists of five line segments as shown below. Given
ivolga24 [154]

Answer:

B

Step-by-step explanation:

f(0) - f(-3) = area under f'(x) from x=0 to x=3.

We can find the area under f'(x) in this interval by finding the area of the triangle formed by the line.

A = 1/2 b h

A = 1/2 (3) (3)

A = 4.5

f(0) - f(-3) = 4.5

Since f(0) = 7:

7 - f(-3) = 4.5

f(-3) = 7 - 4.5

f(-3) = 2.5
