c one is the correct answer
Answer:
the free
Step-by-step explanation:
V≈254.47
Which rounded to the nearest tenths place, is 254.5
The equation to find the volume of a cylinder is V=πr^2h, so if we input 3 into where r is, and if we input 9 in the place of h, we get V=π(3^2)9
If we solve the exponent, now it’s V=(π9)9. So now we multiply pi by 9, then that by 9, and you get 254.47
A ) 40
2^2=4
6^2=36
4+36=40
Answer:
D)
Step-by-step explanation:
You have to use the laws of exponents to solve this:
Power of a Power: . In this case, , all of the numbers in the parenthesis need to be multiplied to the power of 3: .
Quotient of Powers: . In this case, , all of the exponents need to be subtracted (but the 4³ (64) and 8 need to be divided): .
Use the Power of a Power again for the expression at the right: . You get: . Keep the subtraction/negative sign where it is.
Together, you get: .
