Question

A cylindrical container of height 18 cm is open at one end. If the radius of the
circular end is 10 cm, what is the external surface area, correct to 2 decimal places?

Answer 1

Answer:

Step-by-step explanation:

A = πR² + 2πRh

A = πR(R + 2h)

A = π(10)(10 + 2(18))

A = 460π

A = 1,445.1326...

A = 1445.13 cm²
