Answer:
150.8
Step-by-step explanation:
Volume of big cylinder = pi * r^2 * h
small cylinder has a radius half the lenght of big cylinder, so height is also half of the big cylinder, since they are similar
so volume of small cylinder= pi * (r/2)^2 * h/2 = (pi * r^2 *h)/8= 1206/8= 150.75
.9999 rounded to the nearest thousandths is 1
hope this helps
Answer:
the distance covered by a car at a constant speed
The unit for area is unit^2. You area for a rectangle is one of the easiest formula in math. A = LW
There’s a few ways to do this. But you essentially want to find the area for each rectangle and add them together.
We can do the two rectangles on the left, bedroom 1 and 3, by doing 3.5 x (4.25+3.75) = 31.5 in^2
Now do bedroom 2, we have to do 7.5 - 3.5 to get the width of the room since it wasn’t given directly. The width is 4 and we have the length of 3.5. Do 4 x 3.5 to get 14 in^2
31.5 + 14 = 45.5 in^2
We’re not done yet because they want it in ft^2 and we’re given 1 inch = 4 feet
Just do 45.5 x 4 to get 182 ft^2
