यदि \(\pi=\frac{22}{7}\), तो (70) सेमी व्यास वाला पहिया (3080) सेमी चलने पर कुल कितने रेडियन घूमेगा?
If \(\pi=\frac{22}{7}\), through how many radians will a wheel of diameter (70) cm rotate after moving (3080) cm?
Explanation opens after your attempt
Correct Answer
A. \(28\pi\)
Step 1
Concept
The wheel circumference is \(70\pi=220\) cm, so it makes (14) revolutions. The total angle is \(14\times2\pi=28\pi\) radians.
Step 2
Why this answer is correct
The correct answer is A. \(28\pi\). The wheel circumference is \(70\pi=220\) cm, so it makes (14) revolutions. The total angle is \(14\times2\pi=28\pi\) radians.
Step 3
Exam Tip
पहिए की परिधि \(70\pi=220\) सेमी है, इसलिए चक्कर (14) होंगे। कुल कोण \(14\times2\pi=28\pi\) रेडियन है।
