The volume of cylinder b is same as cylinder A = 360 cm^3
Answer:
a=1 b=3 c=-4
Step-by-step explanation:
using almighty formular
a=1 b=3 c= - 4
The lateral surface area of a cylinder is:
a=2πrh, we are told that r=1.8ft and h=4ft so
a=2π(1.8*4)
a=2π(7.2)
a=14.4π ft^2
a≈45.24 ft^2 (to nearest hundredth of a square foot)
Estimate this product first. 7 times 2 would be 14; 7 times 3 would be 21. So the actual product must be about halfway between 14 and 21, or 17.5.
The actual product 7*2.6 comes out to 18.2 (which is fairly close to 17.5, but not close at all to 14).
