Calculate 18843

Height 9cm diameter 24cm cone - calculate its volume and surface.

Correct answer:

V =  1357.168 cm3
S =  1017.876 cm2

Step-by-step explanation:

h=9 cm D=24 cm  r=D/2=24/2=12 cm  S1=π r2=3.1416 122452.3893 cm2  V=31 S1 h=31 452.3893 9=1357.168 cm3
s=r2+h2=122+92=15 cm S2=π r s=3.1416 12 15565.4867  S=S1+S2=452.3893+565.4867=1017.876 cm2
