The surface area of the cheese wheel can be calculated by finding the area of the top and bottom circles and the area of the curved side.
The area of the top and bottom circles (which are the same) can be calculated using the formula for the area of a circle: A = πr^2, where r is the radius. The diameter of the cheese wheel is given as 6 inches, so the radius is half of that, which is 6/2 = 3 inches.
A1 = π(3)^2 = π(9) = 28.26 square inches
The area of the curved side can be calculated by finding the circumference of the circle and multiplying it by the height of the wheel. The circumference of a circle is given by the formula: C = 2Ï€r.
C = 2Ï€(3) = 6Ï€ = 18.84 inches
A2 = 18.84 inches * 2 inches = 37.68 square inches
To find the total surface area, we add the area of the top and bottom circles to the area of the curved side.
Total surface area = A1 + A2 = 28.26 square inches + 37.68 square inches = 65.94 square inches
Rounding to the nearest tenth, the total surface area of the cheese wheel is 65.9 square inches.
