Well, just by looking at the beginning of the problem, Jamelia had made the common mistake of thinking that
(<span>8.4852...)
</span>is equal to
(12)
If you want to estimate a square root like 72, simply find squares that would fit around the number you are looking to find, in our case, 72.
So 9*9 is 81, which is too high and 8*8 is 64, which is too low. So you know that somewhere between those numbers is what your root of 72 is!

Answer:
813.4 cm² (nearest tenth)
Step-by-step explanation:
<u>Volume of a cylinder</u>
Given:
- h = 18cm
- V = 1715 cm³
Use the Volume of a Cylinder formula and the given values to find the <u>radius of the cylinder</u>:
<u>Surface Area of a Cylinder</u>
Substitute the given value of h and the found value of r into the formula and solve for SA:
Therefore, the surface area of the cylinder is 813.4 cm² (nearest tenth)
