The inner and outer radii is 3cm and 3.5cm.if length is 56cm find TSA
Answers
in sufficient question........
Answer:
Step-by-step explanation:
Firstly, Inner Curved Surface Area = 2πr(r+h)
= 2×22/7×3(3+56)
= 44/7×177
= 1112.57 cm²
Now, Outer Curved Surface Area = 2πr(r+h)
= 2×22/7×3.5(3.5+56)
= 2×22×29.75
= 119 cm²
Now, The Total Surface Area is = (1112.57+119) cm²
= 1231.57 cm²
Therefore, the Total Surface Area is 1231.57 cm²
