Question

A cylindrical can of popped corn has a lateral surface area of 6760 T

cm? The height of the can is 40 cm. Using your formula chart, find the
correct formula and use it to find the radius.
F. 168 cm
H. 13 cm
G. 84.5 cm
J. 26 cm

Answer 1

9514 1404 393

Answer:

G. 84.5 cm

Explanation:

Assuming the lateral area is 6760π cm², we can find the height from ...

A = 2πrh

r = A/(2πh) = (6760π cm²)/(2π·40 cm) 6760/80 cm = 84.5 cm

The radius of the can is 84.5 cm.
