The volume of the 6 cm sphere is 1.53 = 3.375 times as large.
Volume of a sphere in cubic units = 4/3*pi*radius3
The surface area of a cylinder with a radius of 6cm and a height of 9cm is 565.5 units2
SA = 904.78 cm2
C = ~37.7 cm A = ~113.1 cm2
The volume of the 6 cm sphere is 1.53 = 3.375 times as large.
Volume of a sphere in cubic units = 4/3*pi*radius3
The surface area of a cylinder with a radius of 6cm and a height of 9cm is 565.5 units2
Radius: 6/(2*pi) = 0.9549296586 Surface area: 4*pi*0.95492965862 = 11.4591559 or as 11.459 square cm to three decimal places
Start by finding the volume of the sphere. You know it's radius is 6cm. The volume of the sphere with respect to the radius is: v = 4/3πr3 So you can plug that radius in to get the volume: v = 4/3π(6cm)3 v = 4/3π216cm3 v = 288πcm3 We know that the volumes of the sphere and the cone are equal, and that the base radius of the cone is six centimeters. Using those, we can work out the cone's height. The volume of a cone is calculated as: v = πr2h we already have the volume and radius, so we simply have to rearrange that equation and solve for h v = πr2h h = v / πr2 and simply plug in our values: h = (288π cm3) / π(6cm)2 h = 288cm3 / 36cm2 h = 8cm So the height of the cone is eight centimeters
A sphere with a diameter of 6cm has a volume of 113.1 cm3
Area = pi*62 = 113.097 square cm to 3 dp
The answer depends on what the "6cm" refers to.
SA = 904.78 cm2
C = ~37.7 cm A = ~113.1 cm2
Volume: 4/3*pi*63 = 904.779 cubic cm rounded to three decimal places
It depends on the relationship between the rectangle and the circles.
