Surface of the cone

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

Correct result:

S =  301.4706 cm2


h=8 cm V=301.44 cm3  V=13 S1 h  S1=3 Vh=3 301.448=282625=113.04 cm2  S1=πr2  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
