Given:
radius of cone = r
height of cone = h
radius of cylinder = r
height of cylinder = h
slant height of cone = l
Solution
The lateral area (A) of a cone can be found using the formula:
where r is the radius and l is the slant height
The lateral area (A) of a cylinder can be found using the formula:
The ratio of the lateral area of the cone to the lateral area of the cylinder is:
Canceling out, we have:
Hence the Answer is option B
Answer: -4
Step-by-step explanation:
= -3 + 0 +(-2) + 3 + 2 +(-4)
= -3 - 2 + 3 + 2 - 4
= -4
Answer:
19/25 = 0.76
311/500 = 0.622
5/8 = 0.625
145/8 = 18.12500
Step-by-step explanation:
Divide the first number by the second like 145 divided by 18.
1) in one minute for first wiil be 1/20
the other 1/30, it means that A paint in one minute 1/20 and B 1/30 then A+B in one minute 1/20 + 1/30 = 3+2/60 = 5 / 60, 5/60 = 1/12
if in one min they make 1/12 then in 12 min they paint all the wall
I believe that the answer is 90x+27
