Answer: 1306.5 m^3
Step-by-step explanation:
1. The formula for the volume of a cylinder is: V=r^2h
2. If you substitute the values into the equation, you get
V = pi * 5.7^2 * 12.8 = 1306.5
3. 1306.5 is already to the nearest tenth, so that is the answer.
Answer:
A = -y^2 + 18
y = 9 + (81 - x)^(1/2) and y =9 - (18 - x) ^(1/2)
Step-by-step explanation:
Given:
P = 2 ( l + w)
x = length and y = width
P = 2 (x + y)
36/2 = x + y
x + y = 18
x = 18 - y
<u>Area:</u>
A = x * y
A = (18 - y) * y
A = 18y - y^2
Using quadratic formula (<u>solve for y</u>):
y = 9 + (81 - x)^(1/2) and y =9 - (18 - x) ^(1/2)

Answer:
16.59
Step-by-step explanation:
πr^2/2
radius is 6.5/2 = 3.25
πx3.25x3.25/2= 16.59
Answer:
I think you would put 3,10 1,0 than 0,-2
