Question
<p>&lt;p&gt;If a wheel covers a distance
of 880 m in 40 rotations, then the diameter of the wheel is?&lt;/p&gt;</p>Solution
<p><p>Distance covered in 40 rotations = 880 m</p> <p>Distance covered in 1 rotation = 880/40</p> <p>= 22 m</p> <p>&there4; Distance covered in 1 rotation = circumference of the wheel</p> <p>2&pi;r = 22m</p> <p>2r (diameter) = (22 &times; 7)/22 = 7 m</p></p>
`sqrt(1297)` + 189.99 =?
90.004% of 9500 + 362 = ?
(74.76 ÷ 12.11 X ?)% of 239.89 = 600.19
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
1784.04 - 483.98 + 464.98 ÷ 15.06 = ?3
If tan θ + cot θ = 16, then find the value of tan2θ + cot2θ.
480 ÷ 10 + 18 % of 160 + ? * 9 = 60 * √36
(95.89% of 625.15 + 36.36% of 499.89) ÷ 6.02 = ? – 269.72
11.89 × 2.10 × 4.98 × 4.03 ÷ 7.98 of 15.03 = ?
