It depends on what shape the three numbers are meant to represent.
54pi units^2
Surface Area of a Cylinder = (2 * pi * r2) + (2 * pi * r * h) (2 * pi * 32) + (2 * pi * 3 * 15) ≈ 339.292007
Slant height of the cone = sqrt(32 + 152) = 15.297 Base surface area = π(3)2 = 9π Curve surface area = π(3)(15.297) = 45.891π Total surface area = 9π + 45.891π = 54.891π
The surface area of a sphere with a radius of 15 units is 2,827 units2
A cone with a diameter of 15 and a slant height of 15 will have a total surface area of about 530.14 units2
The approximate surface area of a sphere with a diameter of 15 centimeters is 707cm2
Entire surface area = (2*pi*52)+(pi*10*15) = 628.319 square inches rounded to 3 decimal places
Surface Area = 417.62123 units2
Use the formula: Surface Area = pi * r * (r+s) where * means multiple, r is the radius and s is the slant height. In this case SA = pi * 3 * (3+15) = pi * 3 * 18 = pi * 54 = 169.646 sq units.
The height makes no difference to the surface area, which is 25*15 = 375 square metres.The height makes no difference to the surface area, which is 25*15 = 375 square metres.The height makes no difference to the surface area, which is 25*15 = 375 square metres.The height makes no difference to the surface area, which is 25*15 = 375 square metres.
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.
Total surface area = (2*pi*62)+(12*pi*15) = 791.681 square cm to 3 d.p.
