9 yards
If the radius of a sphere is tripled, the surface area increases by (3)2 = 9 times, and the volume increases by (3)3 = 27 times.
Surface = 9*pi yd2 Therefore radius = 1.5 yards and so volume = 4.5pi yd3 or 14.137 yd3
Assuming you have a cylinder, the volume is area of the base multiplied by the height. The area of the base is the area of a circle of radius 3 (PI*radius^2 = PI*3^2 = 9*PI). The height is 5. The resulting volume would be 5*9*PI = 45*PI units^3. Did I just do your homework?
The volume increases to 9 times as much.
A sphere with a radius of 9 units has a volume of 3,053.63 units3
Volume of the sphere: 4/3*pi*9^3 = 972*pi cubic units
The volume of a sphere whose radius is 9 meters is: 3,054 meters3
The volume is 3,053.63 mm3
The sphere's surface area is ~1,017.9 square units.
the volume of a sphere is 4/3 (pi) r^3, so if r= 9 then volume would be approximately 3053.63m
A cylinder with a base radius of 4 units and a height of 9 units has a volume of 452.39 units3
V = 3,054 cm3
3,053.6 cm^3
V = 3,054 cm3
Volume= 4/3 * pi * r^3 (where * means multiply and ^3 means cubed So for a sphere of radius 9 Vol = 4/3 * pi * 729 = pi * 972 = 3,053.628 cubic units. Surface area = 4 * pi * r^2 (where ^2 means squared So for a sphere of radios 9, the SA = 4 * pi * 81 = pi * 324 = 1017.876 square units
V = 3,053.6 cubic meters.
