Answer: C
Step-by-step explanation:
To find the surface area of a cone, you use the formula
. Since we are already given the height and radius, all we have to do is plug in the values and solve.
[solve inside of square root]
[parenthesis]
[multiply]

Therefore, the closest answer is C.
Hello from MrBillDoesMath!
Answer:
36
Discussion:
36 = 6^2 so is a power of 6
The other choices are multiples of 6 not powers of 6 (e.g. 24 = 6*4, 12 = 6*2, 18 = 6*3)

nk you,

Answer: Maybe 5.7
Step-by-step explanation: To solve this we are going to need to understand the pythagorean theorem. we can use it as a way to find this certain side. if we put these numbers in the theorem, we get a^2+49=81 (7^2=49 and 9^2=81), we can subtract 49 on both sides and get 32. We would also need to take out the power of 2 on the side of the a^2, so you would do the square root of a^2, which would just become a and the square root of 32, which if you crunch the numbers on a calculator. You would get 5.656..... then you round it to the nearest tenth and get 5.7.
Answer:
C. 
Step-by-step explanation:
The polynomial form that reveals most quickly the zeroes is the form of a product of binomials. That is:

Where
is the product function and
is the i-th root of the polynomial.
Hence,
resembles a form that is close to the form described above. The right option is C.
8+7 = 14+3 is the false answer
