Answer:
A. Surface Area = 3.14 × (2 × 3 + 2²)
B. Surface Area = 31.4 (unit)²
Step-by-step explanation:
A. The expression used for calculate the surface area of the cone is:
Surface Area = 3.14 × (r×s + r²)
If r = 2 and s = 3
then, Surface Area = 3.14 × (2 × 3 + 2²)
B. Surface Area = 3.14 × (2 × 3 + 2²)
⇒ Surface Area = 3.14 × (6 + 4)
⇒ Surface Area = 3.14 × (10)
⇒ Surface Area = 31.4 (unit)²
