The answer is 1808.64 ft²
To calculate area of square we need to find radius r. Radius is a half of a diameter:
r = d/2
The blueprint:
d = 18 cm
r = 18/2 = 9 cm
<span>The blueprint has a scale of three centimeters to four feet. Actual radius r1 is:
</span>3 cm : 4 ft = 18 cm : r1
After crossing the products:
r1 = 4 ft * 18 cm : 3 cm
r1 = 24 ft
The area of the circular base of the fountain is:
A = r1² * π
π = 3.14
r1 = 24 ft
A = 24² * 3.14
A = 1808.64 ft²
Answer: y=4
Step-by-step explanation:
8y+1=6y+9 -Because y is equal the equations are as well.
2y+1=9- Take 6y to the other side by -6y
2y=8-Take one over by -1
y=4-Divide 8 by 2 to get y=4
