The volume of a cylinder is r^2

dh
enter values, then you get 3.53, multiply that by the BTU, the answer is 8888 BTU
Answer:
0
Step-by-step explanation:
-7+1+ -1 * -6
Using PEMDAS, we multiply and divide first
-1*-6 = 6
Then we add and subtract from left to right
-7+1+ 6
-6+6 =0
Answer: 40%
Step-by-step explanation:
To write 8/20 as a percent have to remember that 1 equal 100% and that what you need to do is just to multiply the number by 100 and add at the end symbol % . 8/20 * 100 = 0.4 * 100 = 40% And finally we have: 8/20 as a percent equals 40%
Answer:
d
Step-by-step explanation:
Given y is directly proportional to x² then the equation relating them is
y = kx² ← k is the constant of proportion
To find k use the condition y =
when x =
, then
= k(
)² =
k ( multiply both sides by 8 )
1 = 2k ( divide both sides by 2 )
k = 
y =
x² ← equation of proportion
When y =
, then
=
x² ( multiply both sides by 2 )
9 = x² ( take the square root of both sides )
x = ±
= ± 3
with positive value x = 3 → d
Michael worked 4.5 hours. 65.75 - 36.50 = 29.25, therefore, Michael made $29.25 not including tips. 29.25/6.50 = 4.5
