Answer:
A≈452.39
Step-by-step explanation:
Area of circle =
πr²
= π12²
Perimeter is the sum of all the 4 sides:
Perimeter = L + L + W + W
Given Width = 10 and Perimeter = 68
L + L + 10 + 10 = 68
2L + 20 = 68
2L = 68 - 20
2L = 48
L = 48 ÷ 2 = 24
Length = 24 inches
I think its C how many tiles will he use to cover the whole section
Place a point at (0,-5) because that is the y-intercept (the -5 on the vertical line)
Since the slope is negative two which can be re-written as -2/1 (rise/run) you go down two and to the right once or up two and to the left once, it doesn't matter which. Another point can be placed at (1,-7) or (-3,-1), it still doesn't matter which.
Then you can draw a line connecting the two points.
I hope this helps :)
