Answer:
50.24
Step-by-step explanation:
diameter is 8 inches
radius is 4
formula:
area = pi times radius squared
area = pi times 4 squared
area = pi times (4 times 4)
area = 3.14 times 16
area = 50.24
Answer:
12 m²
Step-by-step explanation:
Area of the floor:
area = length * width
area = 4 m * 5 m
area = 20 m²
area of carpet = 60% of area of the floor
area of carpet = 0.6 * 20 m²
area of carpet = 12 m²
Answer:
x = 44
Step-by-step explanation:
this is a proportion which you can solve by cross-multiplying:
6x = 24·11
6x = 264
x = 264/6
x = 44
Answer:
x^2 - 5x - 66
Step-by-step explanation:
1. Distrubute the x to the x and -11 so you will get x^2 - 11x
2. Distrubute the 6 to x and -11 and you get 6x - 66
3. Combine like terms (x^2 - 11x + 6x - 66) you will get x^2 - 5x - 66
