Answer:

a = 5.5

Step-by-step explanation:

3 (40 - 2) + 5 = 12a - 1

120 - 60 + 5 = 12a - 1

60 + 5 = 12a - 1

65 = 12a - 1

66 = 12a

5.5 = a

a = 5.5

A cylinder has a volume of 864 in3 and a radius of 12 in. What is the height of the cylinder?

Firlakuza [10]

Cyl. vol.: V = pi*r^2*h

Here,

V = 864 in^3 = pi*(12 in)^2*h

864 in^3
so that h = --------------------- = 1.91 inches, or approx. 2 inches.
3.14*144 in^2

I have to find the area of this rectangular prism pls help!!

Nina [5.8K]

Answer:

the surface area is 208

Step-by-step explanation:

formula for surface area is A = 2 (w*l + h*l + h*w )

A = 2 ( 4*8 + 6*8 + 6*4 )

A = 2 ( 32 + 48 + 24 )

A = 2 ( 104 )

A = 208

A cylinder vase has a height of 10 inches and a diameter of 3 inches. If the water raises to 9/10 of the way to the top, approxi

Answer:

The volume of water in the vase is $64 in^3$

Step-by-step explanation:

A cylinder vase has a height, h, of 10 inches and its diameter of 3 inches. This means that its radius, r, is:

r = 3 / 2 = 1.5 inches

To find the volume of the water in the vase if the water raises to 9/10 of the way to the top, we first have to find the volume of the vase when it is filled with water and then, find 9/10 of that volume.

The volume of a cylinder is given as:

$V = \pi r^2h$

The volume of the vase will be:

$V = \pi * 1.5^2 * 10\\V = 70.69 in^3$

Hence, the volume of the water in the vase when it is 9/10 filled is:

$\frac{9}{10} * 70.69 = 63.62 in^3$

Approximating to the nearest cubic inch, the volume of water in the vase is $64 in^3$
