The formula for a cylinder's volume is
V = π r² h
V = 1345.6
π = 3.14
r = 5.8 cm
1345.6 = 3.14 * 5.8^2 h Multiply 3.14 and 5.8^2 together.
1345.6 = 105.6 h Divide by 105.6
1345.6 / 105.6 = h
h = 12.73 cm <<<< answer.
I don't see anything wrong with what I've done but I don't see the answer anywhere. Estimating 1345 can be rounded to 1300.
pi * 5.8^2 = 3 * 35 = 105 which we could round to 100.
1300 / 100 about = 13 So the answer should be in the region of 100.
I cannot see any reason to believe there is an error. If there is something that has not been copied correctly, I'd like to know what it is.
First subtract the two numbers:
8 - 5 = 3
Now divide this to the original:
3 / 5 = 0.6
Multiply by 100:
0.6 * 100 = 60%
Answer:
A7.45x = y
Step-by-step explanation:
We can use a ratio to solve this problem. Take the total cost of the lunches and divide by the number of lunches.
y = total cost of lunches and
x = number of lunches
74.50 y
-------------- = ------------
10 x
Using cross products
74.5 x = 10 y
Divide each side by 10
74.5/10 x= 10y/10
7.45x = y
Answer:
1. 20
2. 23
3. 6
Step-by-step explanation:
We have that:
f(x) = 2x
g(x) = x² + 1
f(g(x)) is the composite function of f and g. So
f(g(x)) = f(x²-1) = 2(x²+1) = 2x² + 2
1. f(g(3))
f(g(x)) = 2x² - 2 = 2(3)² + 2 = 18 + 2 = 20
2. f(3)+g(4)
f(3) = 2(3) = 6
g(4) = 4² + 1 = 17
f(3) + g(4) = 6 + 17 = 23
3. f(5) - 2g(1)
f(5) = 2(5) = 10
g(1) = (1)² + 1 = 2
f(5) - 2g(1) = 10 - 2*2 = 10 - 4 = 6
