Answer:
= 1099 cm^2
Step-by-step explanation:
The surface area of a cylinder is found by using the formula
SA=2πrh+2πr^2
We know the diameter. To find the radius, we take the diameter and divide by 2.
r =d/2
r =14 cm/2 = 7 cm
h = 18 cm
Substituting what we know
SA = 2 * pi * 18 * 7 + 2 * pi * (7)^2
= 252 *pi + 2* pi *49
= 252 pi + 98 pi
= 350 * pi
Let pi be approximated by 3.14
SA = 350 * 3.14
= 1099 cm^2
6*8=48 total objects............
1 km=0.621mi
xkm=106 mi
x=106/0.621=170.66
b is the answer
Y/9=44/54
9(Y/9)=9(44/54)
Y=7 1/3 or 22/3
0.7 is seven tenths.
Seven tenths as a fraction is 7/10.
Hope this helps!
