Answer:
184.96
Step-by-step explanation:
V = (base × height) ÷ 3
base = pi × radius^2
2 × pi × radius = circumference
2×pi×r = 29.516
÷2 ÷2
pi×r = 14.758
÷3.14 ÷3.14
r=4.7
base= 3.14 × 4.7^2
= 69.36
V = (69.36 × 8) ÷ 3 = 184.96
5. 25 = x + 3
It is a one step equation. You just need to subtract 3 on both sides to get x.
6. 2b - 7 = 15
This is a two step equation. You need to add 7 on both sides and then divide both sides by 2 to get b.
7. 10m = 90
Finally, this is a one step equation. You need to divide both sides by 10 to find m.
Answer:
Step-by-step explanation:
The formula for the volume of a cylinder is
V = πr²h
Data:
V = 20 000 gal
h = 34.5 ft
Calculations:
I assume the gasoline tank is lying on its side, so we are asked to find the diameter of the tank.
(a) Convert the volume to cubic feet
V= 20 000 gal × (1 ft³/7.48 gal) = 2674 ft³
(b) Calculate the radius of the tank
V = πr²h
r² = V/(πh) = 2674/(π × 34.5) = 24.67 ft²
r = √24.67 = 4.967 ft
(c) Calculate the diameter of the tank
d = 2r = 9.934 ft
(d) Calculate the length of the measuring pole
l = d + 1 = 9.934 + 1 = 
<span>The property that is shown in the expression given in the question is commutative property. The word commutative has basically been taken from the word "commute". This means moving around and in case of this problem, it means moving around for doing the addition and getting to the right answer. I hope it helps you.</span>
She spent 17 hours tutoring
$210 = 7 hours
$20 x 10 hours = $200
$210 + $200 = $410
7 Hours + 10 Hours = 17 Hours
