2x^2+5x-12
Answer:
m = 3/20
Step-by-step explanation:
3/5 = 4m
3/(5*4) = m
3/20 = m
Check
3/5 = 4*3/20
3/5 = 12/20
Normally, to find the area of a circle you'd do π ×

so you have to find the radius by dividing 5 by 2 to get 2.5. Approximating pi as 3.14, you would do 3.14 ×

= 19.625. Because the porch is a quarter circle, you would then divide this by 4 to get 4.906. Rounded to the nearest square foot, your answer would therefore be 5 ft. I hope this helps!
