The circumference of a circular track is 154m. find the diameter of the track. (take π=22÷7

The diameter of the track is 49 m.

Step-by-step explanation:

The circumference of the track = 154 m

The Circumference of a Circle =  2 π r

⇒

⇒

or, radius of the circle = 24.5 m

Now, Diameter =  2 x Radius

or, Diameter  =  2 x 24. 5 m

                       =  49 m

Hence, the diameter of the track is 49 m.

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%
