Question

A car wheel makes six and a half turns. Find the number of right angles through which it turns​

Answer 1

Answer:

26 number of right angles.

Step-by-step explanation:

In one half turn wheel rotates about an angle of 180⁰.

In one fourth turn wheel rotates at an angle of 90⁰

So in one turn wheel rotates an angle of 90⁰ 4 times

Therefore 90⁰ rotated in 6 turns = 6×4 = 24

And in half turn angle rotated is 2 times

Total angle rotated = 24+2 = 26

Answer 2

Answer:

1 turn = 4 right angles

∴ 4 turns = 4 × 4 = 16 right angles and

$\frac{1}{2}$

turn = 2 right angles.

So, the number of right angles in four and half turns = 16 + 2 = 18
