Question

The circumference of a circular track is 154m. Find the diameter of the track take x 22/7

Answer 1

Answer:

As we Know the circumference of the circle is $\pi$d

154=$\pi$d

154=22/7·d

154×7/22=d

7x7=d

49=d

So our diameter is 49m.

Answer 2

49 cm

Step-by-step explanation:

Given:

Circumference circular track = 154 cm

To find:

Diameter of track

Solution:

As we know,

Circumference of circle = dπ

[where d = Diameter of circle]

or, d = circumference/π

$= \frac{154}{ \frac{22}{7} } \\ \\ = 154 \times \frac{7}{22} \\ \\ = = \cancel{154} \times \frac{7}{ \cancel{22}} \\ \\ = 7 \times 7 \\ \\ 49 \: \: \: \textsf{cm}$

Therefore, the required diameter is 49 cm.
