Calculate the slant height for the given cone. Round to the nearest tenth. Diameter = 18cm Height= 7cm
11.2 cm
12.5 cm
14.8 cm
11.4 cm

show work on how you got the answer :)

draw a side view. Note that if you drop an altitude to the center of the base of the cone, the slant height s is given by

s^2 = 9^2 + 7^2
Answered by Damon
radius at base = 18/2 = 9
height at center = 7

slant height = hypotenuse = sqrt (81+49)
