Answer:
V = 7.81 cubic inches
Step-by-step explanation
The formula for right circular cone is
V = πr^2 h/3
V = volume of the cone
π - pie
r = radius of the cone
h = height of the cone
We are provided with
h = 2.3in
d = 3.6in
π = 22/7
First, we calculate the radius
d = 2r
r = d/2
r = 3.6/2
r = 1.8
Then we can use the formula
V = πr^2h/3
V = 22/7 * 1.8^2 * 2.3/3
V = 3.142 * 3.27 * 0.767
V = 7.80812136 cubic inches
According to the question, we are asked to round off to nearest tenth cubic inches
V = 7.81 cubic inches

Answer:
x = 1
Step-by-step explanation:
3(2x - 1) + 2 = 5x
Distributive
6x - 3 + 2 = 5x
6x - 1 = 5x
6x - 5x = 1
x = 1
