Hi there!
The formula for the lateral area of a cylinder is LA = 2 x pi x r x h. (two times pi times radius times height) Using this formula, we can plug in the values and solve for the lateral area.
Plugging in the values: LA = 2 x pi x 7 x 9
Simplifying: LA = 2pi x 63
LA = 126pi yd^2
ANSWER:
The 4th option - 126pi yd^2
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
8.6 cm
Step-by-step explanation:
V=pi r-squared h
diameter of 10 means radius of 5
675.1=3.14x5x5xh
675.1=78.5h

M(N+2)+3N+6
M*(n+2)+3(n+2)
Answer
(n+2)*(m+3)
Answer:
$11.25
Step-by-step explanation:
Multiply the number of hours she works by how much she gets paid per hour.
800
Multiply 50 times 7 (50 being the amount charged for her kid and 7 being the days of the week)
350
Subtract the 350 from the 800
450
Divide the 450 by the number of hours worked per week
450/40
Answer: 11.25
So Sally actually makes 11.25 per hour.
