Question

Area of the curved surface of a pipe is 0.384 cm^2.Find the radius of the base of the pipe if its length is 2 cm.​

Answer 1

Answer:

i think it should be 50

but im not sure

Answer 2

Step-by-step explanation:

Curved surface area =

$2 \times \pi \times r \times h$

= 0.384 cm^2

Height = 2cm

2 × 22/7 × r × 2 = 0.384

88/7 × r = 0.384

r = 0.384 × 7/88

so, r = 0.0305 (estimated)
