Surface of the cone

Calculate the cone's surface if its height is 8 cm and the volume is 301.44 cm3.

Correct answer:

S =  301.4706 cm2

Step-by-step explanation:

h=8 cm V=301.44 cm3  V = 31 S1 h  S1=h3 V=83 301.44=252826=113.04 cm2  S1 = π r2  r=S1/π=113.04/3.14165.9985 cm  s=r2+h2=5.99852+829.9991 cm  S2=π r s=3.1416 5.9985 9.9991188.4306 cm2  S=S1+S2=113.04+188.4306=301.4706 cm2
