A runner runs around a circular track with a radius of 50m.if he runs half way round the track from a to b.am i correct if i say his distance is 100m?

No, not if he ran around the track half way.

half way around a circle is radius*PI

C = 2pi*r = 6.28 * 50 = 314m/rev = The

Crcumference = The distance around the track.

d = 1/2 * 314m = 157m.

No, you are not correct. When the runner runs halfway around the circular track from point A to point B, he covers an arc length equal to half the circumference of the circle.

To find the distance, we can use the formula for the circumference of a circle:

Circumference = 2 * π * radius

In this case, the radius is 50 m. Therefore, the circumference of the circle is:

Circumference = 2 * π * 50 = 100π m

Since the runner runs halfway around the track, the distance he covers is half of the circumference:

Distance = (1/2) * (100π) = 50π m

So, the correct answer is that the runner's distance from point A to point B is 50π meters, which is approximately equal to 157.08 meters.

No, your statement is not correct. When the runner runs halfway around the circular track, the distance he covers is not equal to the circumference of the entire track, which would be 100 meters in this case. Instead, the distance covered by the runner is equal to half of the circumference of the circle.

To calculate the distance covered by the runner, we need to find the circumference of the circular track. The formula for the circumference of a circle is C = 2πr, where C is the circumference and r is the radius.

In this case, the radius of the track is given as 50 meters. Substituting this value into the formula, we get:

C = 2π(50)
C = 100π

The circumference of the circular track is 100π meters.

Since the runner runs halfway around the track, the distance covered would be half of the circumference, which is:

Distance = (1/2) * 100π

Simplifying this expression:

Distance = 50π

So, the correct distance covered by the runner is 50π meters, or approximately 157.08 meters, not 100 meters.
