Victoria purchased candy at a convenient store. The candy comes in a right cylinder as illustrated in the image below. The height of the cylinder is 18.5 inches and the diameter of the cylinder is 2.75 inches. What is the area of "one" of the circular faces of the cylinder? Use the area formula for a circle: (A = π x r x r)
A .Area of Circular Face = 5.9 inches squared
B. Area of Circular Face = 23.7 inches squared
C. Area of Circular Face = 8.6 inches squared
D. Area of Circular Face = 32.8 inches squared

Answer:

The area of the circular face is 5.9 in²

Step-by-step explanation:

radius = half of diameter

d = 2.75in

r = 2.75in / 2 = 1.375in

To solve this problem we need to use the area formula of a circle:

a = area

r = radius = 1.375in

π = 3.14

a = π * r²

we replace with the known values

a = 3.14 * (1.375in)²

a = 3.14 * 1.89in²

a = 5.9 in²

The area of the circular face is 5.9 in²
