Answer:
180
Step-by-step explanation:
Triangle: 1/2BH
Square: BH
1. Split up the shapes
2. Use the area formula for square and triangle
Square area: 135
Triangle area: 45
3. Add
Area of a square is given by multiplying the length by the width, but since a square has four sides of equal length, we will end up multiplying two numbers that are the same.
We want a minimum area of 80 square feet and at the maximum of 125 square feet
Think of the square numbers that are in between 80 and 125
8 × 8 = 64
9 × 9 = 81
10 × 10 = 100
11 × 11 = 121
12 × 12 = 144
There are three possible measurements of the patio:
9 by 9 and number of tiles left = 125 - 81 = 44 tiles
10 by 10 and number of tiles left = 125 - 100 = 25 tiles
11 by 11 and number of tiles left = 125 - 121 = 4 tiles
Answer:
Step-by-step explanation:
To find the total surface area of the cylinder
We get
S.A=2πr^2+2πrh
S.A=2×3.142×4×4+2×3.142×4×10
S. A=100.544inches sq+251.36inches sq
S. A=351.904inches sq
