Calculate 32311

Calculate the volume and surface of a cone with a base diameter of 10 dm and a side of 13 dm.

Correct answer:

S =  282.7433 dm2
V =  314.1593 dm3

Step-by-step explanation:

D=10 dm s=13 dm  r=D/2=10/2=5 dm s2 = h2+r2 h=s2r2=13252=12 dm  S1=π r2=3.1416 5278.5398 dm2 S2=π r s=3.1416 5 13204.2035 dm2  S=S1+S2=78.5398+204.2035=282.7433 dm2
V=31 S1 h=31 78.5398 12=314.1593 dm3
