Answer:
Surface are = 94.24 cm2
Cylinders =4,244
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a cylinder = 2π (diameter/2) h + 2π (diameter /2)²
Replacing with the values given
s = 2π (2/2) 14 + 2π (2/2)²
s = 87.96+ 6.28 =94.24 cm2
Since:
1 m2 = 10,000 cm2
40 m2 = 400,000 cm2 (area that one can of paint covers)
We have to divide the area that one can of paint covers by the surface area of each cylinder:
400,000/94.24 = 4244 cylinders
Answer:
A
Step-by-step explanation:
calculate 20% of $88
× $88 = 0.2 × $88 = $17.60
We know that
scale factor=measure larger triangle/measure smaller triangle---->18/12
scale factor=1.5
so
measure larger triangle=scale factor*measure smaller triangle
for the leg in the smaller triangle equal to 5
measure larger triangle=1.5*5-----> 7.5
the answer is
7.5
Answer:
If you buy a diaper online instead of Babies-R-us, you save 4 cents more.
Step-by-step explanation:
If 56 diapers cost 28
then 1 diaper cost x
56x = 28
x = 28/56
x = 0.5 or 50 cents
If 112 diapers cost 52
then 1 diaper cost x
112x = 52
x = 52/112
x = approximately 46 cents.
Add up the two acres 60 3/4
then multiply by 4/5 and you get 48.6
that should be your answer.
