The formula for the surface area of a cylinder is:
Plug in what we know, use 3.14 to approximate for pi(radius is half the diameter, 30/2 = 15):
Simplify:
Subtract 1413 to both sides:
Divide 94.2 to both sides:
So the height is approximately 45 millimeters.
Answer:
this only goes to the thousanths.
Step-by-step explanation:
Answer: That would be 549.5 cubic inches of cat litter (approximately).
Step-by-step explanation: The cylindrical storage container has a height of seven inches and a radius of five inches. To know how much cat litter would fill it requires us to calculate the volume of the container.
The volume of a cylinder is given as,
Volume = Pi x r^2 x h
Where r is the radius, h is the height and Pi shall be taken as 3.14
We can now substitute for the known values as follows;
Volume = 3.14 x 5^2 x 7
Volume = 3.14 x 25 x 7
Volume = 549.5
Rounded to the nearest tenth, the container would be filled with 549.5 cubic inches of cat litter.
Answer:
22
Step-by-step explanation:
so permeter of a square is the sum of all the sides
94=5x+5x+4x+2+4x+2
so x=5
then simply subistitue 5 in 4x+2
4(5)+2
=22
