Answer:
(4, 5)
Step-by-step explanation:
y = 2x - 3
y = 7 - 0.5x
y is already isolated on both equations, set them equal to each other:
2x - 3 = 7 - 0.5x
add 3 to both sides:
2x = 10 - 0.5x
add 0.5x to both sides:
2.5x = 10
divide by 2.5:
x = 4
plug in 4 for x on either equation and solve for y:
y = 2(4) - 3
y = 8 - 3
y = 5
(4, 5)
To get the answer divide the diameter by two, so you can get the radius. So plug it into the formula A=π
8²=π
(8²)=64π
=200.96 and for multiplying pie I just used 3.14 instead the entire number so I could get it by having the decimal in the hundredths place.
2.57 would be the correct answer I am confident!
