Calculate 32321

The shell of the cone is 62.8 cm2. Calculate the length of the side and height of this cone if the diameter of the base is 8 cm.

Correct answer:

s =  5 cm
h =  3 cm

Step-by-step explanation:

P=62.8 cm2 d=8 cm  r=d/2=8/2=4 cm  S1=π r2=3.1416 4250.2655 cm2  P=π r s  s=π rP=3.1416 462.8=5 cm
s2=h2+r2  h=s2r2=4.9975242=3 cm
