Answer:
18.8
14+12+21+26+19+15+22+17+24+18 = 188 188/10
I don't remember how to do stem and leaf plots.
Answer:
The larger canister has 8 times the volume and 4 times the volume of the smaller one.
Step-by-step explanation:
The smaller canister has a diameter of 9 cm (radius = 4.5 cm) and height of 12 cm.
The larger canister has double the diameter and height of the smaller one. The diameter of the larger canister is 18 cm (radius = 9 cm) and height of 24 cm.
The canisters are in the shape of a cylinder.
The volume of a cylinder is given as:
The surface area of a cylinder is given as:
A = 2πr(r + h)
SMALLER CANISTER
Volume = π * 4.5 * 4.5 * 12 = 763.41 cubic centimetres
Area = 2 * π * 4.5(4.5 + 12) = 2 * π * 4.5 * 16.5 = 466.53 square centimetres
LARGER CANISTER
Volume = π * 9 * 9 * 24 = 6107.26 cubic centimetres
Area = 2 * π * 9(9 + 24) = 2 * π * 9 * 33 = 1866.11 square centimetres
By reason of comparison, the larger canister has 8 times the volume and 4 times the volume of the smaller one despite having double the dimensions.
The figure is made up of a triangle and a semicircle.
The triangle has base 3.6 ft and height 4.8 ft.
The semicircle has diameter 3.6 ft, so its radius is 1.8 ft.
The total area is the area of the triangle plus the area of the semicircle.
A = bh/2 + pi * r^2/2
A = (3.6 ft) * (4.8 ft)/2 + 3.14 * (1.8 ft)^2 / 2
A = 8.64 ft^2 + 5.0868 ft^2
A = 13.7 ft^2
