To find the area of a cement figure, we calculate the area of the base and the sides separately, then add them together. The total area is approximately 392.5 square feet.
Step-by-step explanation:
To find the area of a cement figure being painted, we need to calculate the areas of the base and the sides separately. The area of the base is given by the formula A = πr^2, where r is the radius. The area of the sides can be calculated using the formula A = bh, where b is the circumference of the base and h is the height.
Let's assume the radius of the base is 5 feet and the height is 10 feet. First, we calculate the area of the base:
A = π(5)^2 = 25π square feet.
Next, we calculate the area of the sides:
A = (2πr)h = (2π(5))(10) = 100π square feet.
Finally, we add the areas of the base and the sides to get the total area:
Total area = 25π + 100π = 125π square feet. Since π is approximately 3.14, the total area is approximately 392.5 square feet.
