What is the surface area of a cylinder whose height is 14 ft and radius is 6 ft?
754 square feet.
What is the surface area of a cylinder whose radius is 15 and height is 30?
The formular for the surface area of a cylinder is 2(pi)rh + 2(pi)r2 where r=radius and h=height and pi=3.14 SA= 2 x 3.14 x 15 x 30 + 2 x 3.14 x 152 =4239
What is the volume of a cylinder whose radius is 3 feet and whose height is 7 feet?
Volume of a cylinder = πr²hV= 3.14159 × (3)² × 7V= 197.92 ft³
What is the surface area of a cylinder whose end area is 11 and height is 11 rounded to the nearest whole number?
Imagine taking the ends off the cylinder, cutting the side down from end to end and unrolling the side; this creates a rectangle with the height of the cylinder along one edge and the circumference of the end along the other. Thus area of side = circumference × height. The ends of the cylinder are circles, thus: area = π × radius² → radius = √(area ÷ π) circumference = 2 × π × radius → circumference = 2 × π × √(area ÷ π) = 2 × √(area × π) → area side = 2 × √(area × π) × height → surface area of cylinder = 2 × area ends + area side → surface area = 2 × 11 units² + 2 × √(11 units² × π) × 11 units → surface area = 22 + 22 × √(11π) units² → surface area ≈ 22 + 129.33 units² ≈ 151 units²
How can you prove that the volume of a sphere is equal to the volume of a cylinder provided their radii are equal and the height of the cylinder is equal to the diameter of the sphere?
I'm quite sure this is impossible to prove, because the volume of a sphere is not equal to the volume of a cylinder with the same radius and height equal to the sphere's diameter. This can be shown as: Volume of sphere = (4*pi*r3) / 3. Volume of cylinder = pi*r2*h. Here, the height, h, of the cylinder = d = 2r. So, the volume of the cylinder = pi*r2*2r = 2*pi*r3, which obviously does not equal the volume of the sphere. The volume of half a sphere (with radius r) is equal to the volume of a cylinder(whose height is equal to its radius, r) minus the volume of a cone with the same height and radius. Therefore, the volume of a sphere is just double that. If you follow the nearby link, you can see a nice demonstration of that.
