DerKrebs [107]2 years ago
5 0

Step-by-step explanation:

x intercept, y = 0

y = x + 1

0 = x + 1

x = -1

x intercept = (-1 , 0)

y intercept, x = 0

y = x + 1

y = 0 + 1

y = 1

y intercept = (0 , 1)

Can somebody help me with these to questions how do you find the area of the circle
Grace [21]

13)

Circumference (C) = 2π·r

11π = 2π·r

11/2 = r

******************************

Area (A) = π·r²

             =  π·(11/2)²  

            = 121π/4

           ≈ 94.985 in²

14)

diameter = 2r

          42 = 2r

           21 = r

*******************

Area (A) = π·r²

             =  π·(21)²  

            = 441π

           ≈ 1384.74 in²

***************************

$280/1384.74 in²

x = $0.20
