Answer 1

Question :-

•Rima rides his bicycle around a circular track. The radius is 0.3 km. Rima rides 5 times the track. Work out her distance.

Concept :-

• There is a circular track and it's radius is 0.3. It's also given that she rides 5 times the track. It means that she rides 5 times on the circumference of the circular track. So for finding the total distance travelled by her, we have to first find the circumference of the circle.

Given :-

• Radius of the circular track = 0.3 km

• Rima rides 5 times the circular track.

To find :-

• Her total distance.

Solution :-

★ Circumference of the circular track :-

⇒C = 2 × π × r

⇒C = 2 × 3.14 × 0.3

⇒C = 0.6 × 3.14

⇒C = 1.884 km

★ She rides 5 times the Circular track :-

⇒Circumference of the circular track × 5

⇒1.884 km × 5

⇒9.42 km.

Therefore, Rima's distance is 9.42 km.

Joyful learning!!!⛅
