Answer:7.775
Step-by-step explanation:
So u do 130.05 ÷18 =7.225
Now u do 15 - 7.225 = 7.775
7.775 is the money she can still spend for them.
Also u could do 15 x 18 = 270
270 ÷ 2 = 135
ANSWER: 4in^2
Explanation: 4x1=4
Answer:
5026.55in²
Step-by-step explanation:
Area = πr^2
radius (r) is half of the diameter, hence the radius is 40 inches
So after plugging that in, the equation should look like
Area = π(40)^2
A = 1600π ≈ 5026.55
The units for this is in² so just add that in the end
