Find the surface area of the cylinder below. Use the approximation 3.14 for pi. (1 point) Responses 533.8 square centimeters 533.8 square centimeters 628 centimeters 628 centimeters 1,099 square centimeters 1,099 square centimeters 628 square centimeters
To find the surface area of the cylinder, we need to calculate the sum of the areas of the two circular bases and the lateral surface area.
The formula for the surface area of a cylinder is given by:
A = 2πrh + 2πr^2
Given that we should use the approximation 3.14 for pi, let's substitute the values:
A = 2(3.14)(7)(12) + 2(3.14)(7)^2
A = 2(3.14)(7)(12) + 2(3.14)(49)
A = 527.04 + 307.86
A ≈ 834.9
Rounded to the nearest whole number, the surface area of the cylinder is approximately 835 square centimeters.
my answers dosnt have 835
Apologies for the error. Let's recalculate the surface area of the cylinder correctly.
The formula for the surface area of a cylinder is given by:
A = 2πrh + 2πr^2
Given that we should use the approximation 3.14 for pi, let's substitute the values:
A = 2(3.14)(7)(12) + 2(3.14)(7)^2
A = 527.04 + 307.86
A ≈ 834.9
Rounded to the nearest whole number, the surface area of the cylinder is approximately 835 square centimeters. Therefore, the correct answer is 835 square centimeters.
