Find the area of a sphere with radius of 6cm?
The surface area ( A ) of a sphere can be calculated using the formula ( A = 4\pi r^2 ), where ( r ) is the radius. For a sphere with a radius of 6 cm, the area is ( A = 4\pi (6^2) = 4\pi \times 36 = 144\pi ) cm². Therefore, the surface area is approximately 452.39 cm² when using ( \pi \approx 3.14 ).
What is the area of a circle in square centimeters if the radius is 4 cm?
Using 3.14 as Pi the area of circle is: 50.24
What is the cicumference of a circle with a radius of 4 cm?
The formula for the circumference of a circle is 2(pi)(r). From your example, r=4 cm So the answer would be 2(pi)(4 cm), or 8pi cm (this is a little more than 24 cm, since pi=3.14).
If a cylinder is 4cm and the height is 9cm what is the volume?
The volume ( V ) of a cylinder can be calculated using the formula ( V = \pi r^2 h ), where ( r ) is the radius and ( h ) is the height. Given that the diameter is 4 cm, the radius ( r ) is 2 cm. Substituting the values, the volume is ( V = \pi (2^2)(9) = 36\pi ) cm³. Therefore, the volume is approximately 113.1 cm³ when using ( \pi \approx 3.14 ).
What is the surface area of a sphere with a radius of 6 cm?
It is: 4*pi*62 = 144*pi square cm
What is the surface area of a sphere with a radius of 5?
It is: 4*pi*52 = 314.159 square cm to three decimal places

What is the Area of a circle 4 cm?
The formula for area of a circle is pi*r*r. If the circle is 4 cm across then the radius is 2 cm. pi times 2 times 2 is 4pi. Many people use 3.14 as pi. 4 time 3.14 is 12.56 sqcm.

What is the volume of a cylinder with the radius of 4 cm and height of 32 cm?
Volume: pi*42*32 = 512*pi cubic cm
What is the volume of the cylinder 4 cm diameter and 40 cm tall?
Volume = (Pi/4) x d2 x h = (Pi/4) x 16 x 40 = Pi x 160 = 502.655 cu. cm. (to nearest 3rd decimal.
What are the circumference and surface area of a sphere with a volume of 250 cubic cm giving your answers correct to 3 decimal places if necessary?
First we have to find the radius because the circumference = 2*pi*r or pi*d and the surface area = 4*pi*r2 4/3*pi*r3 = 250 cubic cm Multiply both sides by 3: 4*pi*r3 = 750 Divide both sides by 4*pi and then cube root both sides: radius = 3.907963209 cm Circumference = 2*pi*r = 24.55445702 or 24.554 cm Surface area = 4*pi*r2 = 191.9158293 or 191.916 square cm Check: 4/3*pi*3.9079632093 = 250 cubic cm
What is the radius for 16 pi cm2?
4 cm because pi*42 = 16 pi cm2
What is the area of a semicircle if the diameter is 8 cm?
It is: pi*4^2 divided by 2 = 8/pi which is about 25 square cm
