The diameter of the base of a cylindrical can is 5 inches. The height of the can is 7.5 inches. Determine total area of two bases. Round your answer to the nearest hundredth (Use 3.14 for PI.)
A. 19.63 square inches
B. 39.25 square inches
C. 78.50 square inches
D. 157.00 square inches
To find the total area of two bases of the cylindrical can, we first need to find the area of one base and then multiply it by 2.
The formula for the area of a circle is A = πr^2, where r is the radius (half the diameter). Since the diameter is 5 inches, the radius is 2.5 inches.
So, the area of one base is A = 3.14 * 2.5^2 = 3.14 * 6.25 = 19.625 square inches.
Now, to find the total area of two bases, we multiply by 2:
Total area = 19.625 * 2 = 39.25 square inches.
Therefore, the correct answer is: B. 39.25 square inches.
