Answer:
36.6 cm
Step-by-step explanation:
Each side, starting with the one all the way to the left and going anticlockwise.
7 + 4.3 + 7 + 4.3 + 7 + (7 - 4.3 = 2.7) + 4.3 = 36.6
Answer:
A triangles angle always equal to 180 degrees. So if you add up what you already have which is 80+40=120
The perimeter of an equilateral triangle is just 3s as all the sides are, well, equal :) so
P=3s and we are told that P=24.6 so
3s=24.6
s=8.2 cm
Answer:
The volume of this cylinder is 9184.5 cubic feet.
Step-by-step explanation:
The area of a circle is
and the volume of a cylinder with that base is just that area times the height:

Here, we're given the diameter, but we need the radius. The radius of a circle is just half of the diameter:

Next, you can use that radius to calculate the area of the base:

Finally, multiply that by the height to find the volume of the cylinder:

The volume of this cylinder is 9184.5 cubic feet.
