Answer:
1815 pi cm^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h
We know the diameter =22
so the radius is d/2 = 22/2 =11
V = pi (11)^2 (15)
V = pi1815
V = 1815 pi cm^3
Answer:
75 cubic units
Step-by-step explanation:
Bottom layer of a rectangular prism is made up of 15 unit cubes.
Therefore, area of the 15 unit cubes = 15(area of the base of one unit cube)
= 15(1)²
= 15 unit²
Number of layers of unit cubes in the rectangular prism = 5
So the height of the prism = 5 units
Volume of the prism = (Area of the base) × Height
= 15 × 5
= 75 cubic unit
Answer:
-3x + 5
Step-by-step explanation:
"Rise over Run"
(0, 5) => (1,2): Goes down (negative slope) 3 units and right 1 unit.
The Y intercept is 5 so the constant is 5.
The side is (2x+3)? then the area is:
(2x+3)(2x+3) = 4 x^2 + 12 x + 9 if x = 6 then
Area = 4(36)+12(6)+9
= 144 + 72 + 9
= 225, too big :(
