Answer:

2√3

Step-by-step explanation:

5y2+20=80

Step 1: Subtract 20 from both sides.

5y^2+20−20=80−20

5y^2=60

Step 2: Divide both sides by 5.

5y^2 /5 = 60/5

y2=12

Step 3: Take square root.

y=√12

y=2√3

Find the volume of this cylinder. Please help

algol13

Answer:

$\boxed {\boxed {\sf 384 \ ft^3}}$

Step-by-step explanation:

The volume is the space an object occupies. The volume formula for a cylinder is provided and it is:

$V= \pi r^2 h$

Where:

r= radius
h= height

The radius is the distance from the center of the circle to the edge, and it is 4 feet. The height is 8 feet. We are told to use 3 for pi.

r= 4 ft
h= 8 ft
π= 3

Substitute the values into the formula.

$V= (3)(4 \ ft)^2 (8 \ ft)$

Solve the exponent.

(4 ft)²= 4 ft * 4 ft = 16 ft²

$V= (3)(16 \ ft^2)(8 \ ft)$

Multiply the three numbers together.

$V= 48 \ ft^2 (8 \ ft)$

$V= 384 \ ft^3$

The volume of the cylinder is approximately <u>384 cubic feet.</u>
