Question

14. The radius of a circular pipe is 12cm what length of tape is required two wrap once around the pipe
pipe
​

Answer 1

Answer:

75.4 cm tape will be required

Step-by-step explanation:

Radius of the circle = 12 cm

length of tape required to wrap around the pipe = Diameter of the pipe.

Diameter = 2π(radius)

Diameter = 2π ( 12 cm )

Diameter = 24cm × π

Diameter = 24cm × 3.14

Diameter = 75.36 cm

75.4cm tape will be required to wrap around around the pipe

More:

Diameter of a circle = 2 × radius

Area of a circle = π (radius)²

Circumference of a circle = 2π(radius)

Answer 2

GiveN :-

• Radius of the pipe = 12 cm

To FinD :-

• Length of tape required to wrap around the pipe

SolutioN :-

• Length of tape wrap around the pipe is equal to it's circumference

★ Circumference of circle = 2πr

→ 2 × 3.14 × 12

→ 75.36 cm

Length of tape wrap around the pipe is 75.36 cm
