Total surface area = (2*pi*62)+(12*pi*15) = 791.681 square cm to 3 d.p.
PI*15(to the second power)*30 = 21205.75
A cylinder with a diameter of 22 inches and a height of 15 inches has a volume of 5,701.99 cubic inches.
The surface area of a sphere with a radius of 15 units is 2,827 units2
Entire surface area = (2*pi*52)+(pi*10*15) = 628.319 square inches rounded to 3 decimal places
Area = Base*Height so Base = Area/Height = 720/15 = 48 cm
For a right cylinder, if the surface area is 2,072.4 and the radius is 15 the height will be 7 (6.99) units.

The height is 15 (14.99) inches.
The surface area of a right cylinder can be calculated by adding the areas of the two bases and the lateral surface area. The formula for the surface area of a right cylinder is 2πrh + 2πr^2, where r is the radius and h is the height. Plugging in the values 8 for the radius and 15 for the height, the surface area of the cylinder would be 720π square units.
Surface Area = ~4,712.4 ft2
The volume of a cylinder is the area of the base times the height = pi*r2 * h For this cylinder, r = 6 and h = 15. Pi is approximately 3.14 V = 3.14 * 62 * 15 V = 1695.6 units3
To work out this problem you must first calculate the circumference of the cylinder, the radius of 7.5 would give a diameter of 15, pi * d (3.141 * 15) = 47.123889803846898576939650749193 or 47.1 to make things more simple. To get the area you multiply the circumference by the cylinders height, which is 15. Giving an answer of 706.85834705770347865409476123789 or 706.9 to give a more simple answer.
Entire surface area: (2*pi*36)+(12*pi*15) = 252*pi square units
