The method to answer this question is very similar to the one for the question I have linked to below.
I will let YOU do most of the calculations this time!!
Step 1: Find the area of the top or bottom -- also called base:
π r^2 = 3.14 x (3.5^2) = 3.14 x 12.25 =
Step 2: Find the circumference of the base:
2 π r = 2 x 3.14 x 3.5 = C(base) cm
Step 3: Find the surface area of the side of the cylinder:
C(base) x Length = C(base) x 10 = A (side) cm^2
Step 5: Add together the three surface areas:
A(base) + A(base) + A(side) = total surface area in cm^2
BTW, the answer is less than 300 cm^2
