Question
Transcribed Image Text:Find the surface areas of the figures on the right.
(a) Examine the figure to the right. Notice that the two bases are circles.
The area of the one of the circular bases, rounded to two decimal places, is
201.06 ft².
Next, find the perimeter of the bases. Notice that the perimeter of the bases
is the circumference of a circle.
The perimeter of the cylinder, rounded to two decimal places, is 50.27 ft.
The height of the cylinder is 16 ft. Substitute the values of B, p, and h into
the formula for surface area and simplify, rounding to the nearest whole
number.
SA = 2B + ph
C
2(201.06) + (50.27)(16)
≈1206 ft²
(a)
16 ft
