Calculate 82073

Calculate a cone's volume and surface area with base diameter d = 22 cm and body height v = 40 cm.

Correct answer:

V =  5068.4361 cm3
S =  1813.7492 cm2

Step-by-step explanation:

d=22 cm v=40 cm  r=d/2=22/2=11 cm S1=π r2=3.1416 112380.1327 cm2  V=31 S1 v=31 380.1327 40=5068.4361 cm3
