Calculate 44541

Calculate the surface and volume of the cone if you know that the base radius r = 5 dm and the side length s = 7 dm.

Correct answer:

S =  188.4956 dm2
V =  128.255 dm3

Step-by-step explanation:

s=7 dm r=5 dm  s2 = h2+r2 h=s2r2=7252=2 6 dm4.899 dm  S1=π r2=3.1416 5278.5398 dm2 S2=π r s=3.1416 5 7109.9557 dm2  S=S1+S2=78.5398+109.9557=188.4956 dm2
V=31 S1 h=31 78.5398 4.899=128.255 dm3
