Rotating cone

Calculate the volume and the surface area of a rotating cone of base radius r = 2.3 dm and a height h = 46 mm.

Correct answer:

V =  2.5483 dm3
S =  33.5672 dm2

Step-by-step explanation:

s=r2+v2=2.32+0.4622.3455 dm S2=π r s=3.1416 2.3 2.345516.9481 dm2 S=S1+S2=16.619+16.9481=33.5672 dm2
