The volume of a cylinder is pi x r^2 (squared) x h.
H = Height
R = Radius.
Let's replace the letters with our numbers for this problem. (5, 3.14, 9)
Our new problem is 3.14 x 9^2(squared) x 5.
Now, what is 9 squared? We can get this by multiplying our number by itself. 9^2 (squared) = 9 x 9. 9 x 9 = 81. Now our problem is.
3.14 x 81 x 5. Now let's get our calculators out!
3.14 x 81 = 254.34. - 254.34 x 5 = 1271.7
In order to make our answer as a decimal to the hundredths place, we have to add a 0 to the right of our 2nd 7 (in the tenths place). 1271.70 can also be written as 1271.7.
Your answer is: 1271.70
Hello there! Your answer is 2.
When we are given this problem: x + 3 = 8x - 11 we are solving for the value of X. We want to isolate all like terms on one side of the equation. To do this, let's add 11 to the left side so the - 11 cancels out on the right.
x + 3 + 11 = 8x - 11 + 11 - After this, add like terms. (so 3 + 11 and - 11 + 11)
x + 14 = 8x - Now, negative 11 plus positive 11 have canceled each other out, we have to subtract x from the left side.
x - x + 14 = 8x - x
14 = 7x - Our last step is do divide both sides of the equation by 7 to finish isolating x.
14/7 = 7/7x
2 = x.
This is your final answer!
That would be D. Julia bought 3 and 2 and spent 10.07. Marcia bought 2 and 4, and spent 12.98. Hope it helps!!!! :D
Step-by-step explanation:
f(x) = 4x - 7
f(2) = 4(2) - 7
f(2) = 8 - 7 => 1
Karan swam and biked for a total of 1 hour and 45 minutes.
let's say 60=100 for a total of 100 equaling 1 hour.
Therefore, 100+45= <u>145</u>
