Answer:
228 cm²
Step-by-step explanation:
The volume of a cylinder of radius r and height h is given by ...
V = πr²·h
Filling in the given information, we can solve for r:
235.5 = π·r²·12
√(235.5/(12π)) = r ≈ 2.49937 . . . . cm
The area of a cylinder is given by ...
A = 2πr² + 2πrh = 2πr(r +h)
Filling in the radius and height, we can find the area to be ...
A = 2π·2.49937·(2.49937 +12) ≈ 227.698 . . . . cm²
About 228 cm² of aluminum are required to make a typical soda can.
It is the one second from the top. the line is straight (y=-3) until it hits x=-1 then it starts increasing significantly
Answer:
3/2
Step-by-step explanation:
you basically just simplify the exponents first, and then simplify from there.
Answer:
yes it is possible to get a common denominator grater than 12 and still get the right answer.
Step-by-step explanation:
This is because the numerator is always directly corelated to de denominator therefore the fraction wouldn't change because when simplified it is the same fraction as it would be with 12 as the denominator
