Question

number of surfaces of a truncated cone
​

Answer 1

Step-by-step explanation:

The surface area, (not including the base), is:

π∗rr2+h2−−−−−−√

Calculate the surface area of the cone as if it was whole, then subtract from that value, the surface area of the bit at the top that is missing.

Finally, add the surface area of the top and bottom disks
