Area of circle = πr²
Solve for r:
90=πr²
90/π=r²
28.65=r²
5.35=r
radius = 5.35cm
Answer:
m = 3/4
Step-by-step explanation:
We have the points (-2,2) and (2,5). We can use those to calculate the slope:
m = 5 - 2 / 2 - (-2)
m = 5 - 2 / 2 + 2
m = 3/4
Answer:
a=32/a
Step-by-step explanation:
Distribute:
8 x 4= 32 8 x -a = -8a
32-8a=2a
add 8a to both sides:
32-8a+8a=2a+8a
Combine like terms:
32=10a
divide by 10 to get a by itself:
32/10=a
flip it around
a=32/10
The x intercept is (1/9, 0) hope this helps, have a nice day :)
