A can of soup is in the shape of a cylinder with radius 3.8cm and height 11cm what is the surface area of the can to the nearest tenth?
First, you figure out what the area of the top of the cylinder is, which in case is pi times radius squared. Then, you multiply the answer by two. Next, you find the lateral surface area of the cylinder by multiplying the circumference times the height. Since the problem only gives us the radius of the cylinder, we use the formula, two times pi times radius times the height, in order to find the lateral surface area of the cylinder. Now the final step. Add the answer you got for the first step, plus the lateral surface area of the cylinder, and this should give you the surface area of the can of soup.
What is circumference of a circle if the raduis is 11cm?
The circumference of a circle, if the radius is 11cm, is about 69.12cm
What is the circumference of a circle with a radius of 11cm?
C = 69.115 cm
How do you find the volume of a cylinder if the diameter is 9cm and height is 11cm?
By plugging them into the formula for the volume of a cylinder:volume = πr2hwhere:π = ratio of circumference to diameter of a circle (~= 3.142)r = radius of cylinder = diameter ÷ 2h = height of cylinder.That's how to find the volume, this is it actually being found:volume = πr2h= π x (diameter ÷ 2)2 x height= π x (9 cm ÷ 2)2 x 11 cm~= 700 cm3
What is the area of a semi-circle with a radius of 11cm?
It is 1/2*pi*r2 = 190.1 cm2
