Question

Bart is jogging on a circular trail in a state park. The diameter of the trail is 650 meters. What approximate distance does Bart cover in one lap around the park? 1,326,650 meters 331,662.5 meters 2,041 meters 1,020.5 meters

Answer 1

l=2πr
r=d/2=650 m/2 =325 m

l=2π(325m)= 650π meters=650x3.14=2041 meters

Answer 2

The correct option is C. 2041 meters.

Explanation:

Diameter of the trail is given to be 650 meters

So, Radius of the trail is half of the diameter.

⇒ Radius of the trail = 325 meter

We need to find the approximate distance covered by Bart in one lap around the park.

So, we will the circumference of the circle with radius 325 meters

⇒ Circumference of circle = 2π × Radius

= 2 × 3.14 × 325

=2041 meters.

Hence, The approximate distance covered by Bart in one lap around the park = 2041 meters.

Thus, The correct option is C. 2041 meters.
