Question

what do you know about the total surface area of frustum​

Answer 1

Answer:

π l1 (R+r) +πR2 +πr2

Step-by-step explanation:

The total surface area of the frustum of the cone = π l1 (R+r) +πR2 +πr2.

These equation has been derived by using the similarity of triangles property between the two triangles QPS and QAB. Measurement of the volume, surface area and curved surface area like any other measurement depends on the understanding of the subject.

Answer 2

The Total surface area of a frustum is:

$\pi \: l \: (r \: 1 + r \: 2 \: ) \: + \pi \: {r1}^{2} \: + \pi \: {r2}^{2}$
