answer:
area: 40cm²
perimeter = 26cm
step-by-step explanation:
- i do not know which one this is telling you to find so i put both area and perimeter
area:
- know the formula
- formula = l x w
- l = length
- w = width
- plug in what you have
l x w
5 x 8
= 40cm²
perimeter:
- for this you just have to each side
- since this is rectangle opposite sides are equal
5 + 5 + 8 + 8
= 26cm
(parallel cross-sections: "parallel" is a mistake)
The solid with circular bases, and square cross-sections perpendicular to the bases is a cylinder, whose height is equal to the diameter of a base circle.
Check the picture attached.
The radius is 5r, so the height=diameter=10r
Volume(cone)=S(base)*height=

(units cube)
