Answer:
B) 42
Step-by-step explanation:
The area of a cylinder is pi*r^2*h where r is the radius and h is the height. Plugging in 3 for the radius(radius=diameter/2) and 1.5 for height you get area=pi*9*1.5. Assuming pi as 3.14 you get 3.14*9*1.5 which is 42.39 which is approx. 42.
Answer:B 42
V=pi/4 x D^2 x H
3.14/4 x 36 x 1.5 = 42 ft^3
1) area =25
perimeter= 24
2) area=49
perimeter=30
Answer: y = (1 - 0.527)^t
Step-by-step explanation:y=e^(-0.75t)
y=(e^-0.75)^t
y= 0.47236655^t
1 - 0.47236655 = 0.52763345
y = (1 - 0.527)^t
I don't see methmetical calculation
