**Answer:**

3.95 in

**Step-by-step explanation:**

The volume is given by ...

V = πr²h

Solving for radius, we get ...

r = √(V/(πh))

For the given numbers, the radius is ...

r = √(980 in³/(π·20 in)) = 7/√π in ≈ 3.95 in

**The radius of the cylinder is about 3.95 inches**.

**Answer:**

80 degrees

**Step-by-step explanation:**

**Step-by-step explanation:**

1. 3⁴+9=

First you have to do the exponent which will give you 81 then add 9 so you would get 90. (Try to practice)

2.5(d+1)

Distribute. That would give you 5d+5.

3.

3(6m)+m

Distribute 3 to 6m and that would give you 18m+m at them and you would get 19m.

4.

8x-2y+x+x

Add all x's. 10x-2y Would be the answer.

5.

17a+24b

Im not sure cause 17 is a prime number. But if 17 was 16 it would be B.

Hope this helped! Try doing there equations on your own or practicing on your own :)
