Answer:
A=2πrh+2πr2 this is the surface are formula of a cylinder. You already know the scale ratio is 2.5 so the answer is (2.5*surface area formula). For the formula just plug in the values for the radius and the height that is given and solve.
Step-by-step explanation:
6 minutes
15-5=10
10-4=<u>6</u>
sin 30°=8/c
1/2=8/c
c=16.
tan 60°=b/8
√3=b/8
b=8√3.
<em>s = 5.4</em>
2^2 + 5^2 = s^2
s^2 = 4 + 25
s^2 = 29
s = sqrt(29)
s = 5.4
