Answer:
$2.83
Step-by-step explanation:
Diameter of the pool = 24ft
Cost of 1 ft² = $0.15
Area of the pool=?
But the pool is a circular pool,
Area of a circle = Πr² or πd²/4
π = 3.142
Area of the pool = (π * 24) / 4
Area = (3.142 * 24) / 4
Area = 18.85ft²
If 1ft² = $0.15
18.85 = $x
x = (18.85 * 0.15) / 1
x = $2.8275 = $2.83
The cost of the pool is $2.83
Answer:
18
Step-by-step explanation:
Look at all factors of 9 that are even; 18, 36, 54, 72, 90
Next divide 198 by those numbers and the only whole number is from 18.
9 x 2 = 18
198/18 = 11
Answer:
0.875
Step-by-step explanation:
∛343 = 7
∛512 = 8
7÷8=0.875
15 * 0 = -36 + a is your first expression
Solve the equation to find.
Add 36
(15 * 0) + 36 = a
0 + 36 = a
36 = a
Your second equation
24 * 8 * 0 = 36 - b
Add 36
(24 * 8 * 0) + 36 = b
36 = b
36 is the answer
