Answer:
62.8 in2
Step-by-step explanation:
With round pizza we need to
find the area of each pizza in
square inches, then determine
the difference.
The area of a circle is given by:
A = πr2
12 inch diameter, radius = 6
a = π(62) = 36π in2
8 inch diameter, radius = 4
a = π(42) = 16π in2
Difference: 36π - 16π = 20π in2
using 3.14 for pi, the difference is
20(3.14) = 62.8 in2
This is dividing
So 1 mile has 1760 yards so in total
2 miles = 3520 yards and it takes 5 minutes to clean up 200 yards (We divide)
3520 ÷ 200 = 17.6 ( Now we multiply)
17.6 x 5 = 88 minutes or ( 1 hour and 22 minutes)
Answer:
-13/5
Step-by-step explanation:
-4/5 x 7= -28/5
3=15/5
-28/5 + 15/5= -13/5
