A model of a cylindrical fuel tank has a radius of 5 cm and a height of 12 cm. On the model, 1 centimeter represents 1.25 m.
1. What is the scale factor between the model and the fuel tank?
a. 1/125
b. 1/150
c. 1/1.25
d. 4/5
2. Determine the surface area of the fuel tank in square meters. Round to the nearest tenth of a square meter.
a. 66.76 m^2
b. 1043.2 m^2
c. 834.5 m^2
d. 711.8 m^2

1. 100cm is 1m so the answer is a
2. SA= A(top)+A(bottom)+A(side)
= (pi)r^2 + 2(pi)r^2 + 2(pi)rh
=78.5+78.5+377.0
= 534.0 cm^2
remember to convert to m
534x1.25= 667.6m^2
Im assuming you misplaced a decimal so your answer will be a
