Answer:
3.54578755
Step-by-step explanation:
Area of a circle = pi * r^2
Radius (r) = ½ * diameter
½ * 10 = 5
A= pi * 5^2
25 * pi = 78.54 sq inches
10.99 / 78.54 = about 14 cents per sq in (13.99)
Answer:
w = -20
Step-by-step explanation:
-
+ 9 = 13
Shift the (+9) to the other side of the equation. (+9) will turn into (-9).
-
= 13 - 9
= 4
Shift the (÷5) to the other side of the equation. (÷5) will turn into (×5).
-w = 4 × 5
= 20
Multiply both sides of the equation by (-1) so that -w will turn into w.
w = (-1) × 20
w = -20
