Parameters 28521

The basic parameters of the rotating cone are:
Base radius 5 cm
The cone height is 12 cm, and the cone side is 13 cm.
Calculate:
a/volume of the cone
b/cone surface

Correct answer:

V =  314.1593 cm3
S =  282.7433 cm2

Step-by-step explanation:

r=5 cm h=12 cm s=13 cm  S1=π r2=3.1416 5278.5398 cm2  V=31 S1 h=31 78.5398 12=314.1593 cm3
S2=π r s=3.1416 5 13204.2035 cm2  S=S1+S2=78.5398+204.2035282.7433 cm2   Verifying Solution:  s2 = h2 + r2 s2=h2+r2=122+52=13 cm
