Answer:
-392
Step-by-step explanation:
-56 x 7=-392
-392 / -56=7
Answer:
7 ÷ 4
Step-by-step explanation:
Another example would be:
12/3 = 12 ÷ 3
The number at the front will be the numerator while the second number will be the denominator
Well we know that the volume of a cylinder equals (area of base) (height)
225pi=a*9
divide both sides by 9
25pi=a
a=pir^2
25pi=pir^2
cancel out pi
25=r^2
5=r so the length of the radius is 5
The total surface area of the soup can would be
equivalent to the sum of the surface area of the 2 covers plus the surface area
of the side.
Surface area of the 2 covers = 2 π r^2
Surface area of the 2 covers = 2 π (2.5 cm)^2
Surface area of the 2 covers = 39.27 cm^2
Surface area of the side = 2 π r h
Surface area of the side = 2 π
(2.5 cm) (9 cm)
Surface area of the side = 141.37 cm^2
Total surface area = 39.27 cm^2 + 141.37
cm^2
