Find the surface area for the given cylinder. Use 3.14 for π and round to the nearest whole number.

A) 180 ft squared

B)720 ft squared

C) 433 ft squared

D) 135 ft squared

Option C:

Surface area of the given cylinder = 433 ft²

Solution:

Diameter of the base = 6 ft

Radius of the base = 6 ÷ 2 = 3 ft

Height of the cylinder = 20 ft

To find the surface area of the cylinder:

Surface area of the cylinder =

                                               = 433 ft²

Surface area of the given cylinder = 433 ft²

Hence Option C is the correct answer.

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
