Calculate 30971

Calculate the cone's surface and volume if its base diameter is 1 dm and the side length is 13 cm.

Correct answer:

S =  282.7433 cm2
V =  314.1593 cm3

Step-by-step explanation:

D=1 dm cm=1 10  cm=10 cm s=13 cm  r=D/2=10/2=5 cm s2 = h2+r2 h=s2r2=13252=12 cm  S1=π r2=3.1416 5278.5398 cm2 S2=π r s=3.1416 5 13204.2035 cm2  S=S1+S2=78.5398+204.2035=282.7433 cm2
V=31 S1 h=31 78.5398 12=314.1593 cm3
