so he's losing 4/10 of a Kg daily, how many times will that equal 3.2 Kgs? namely how many times does 4/10 go into 3.2?
well, let's firstly convert 3.2 to a fraction, and then divide.

Constant = height/ width
Constant :
1/0.5=2
4/2=2
6/3=2 and so on.
Correct answer is C.2
Circumference<span> = 2 x </span>Radius<span> x Pi C = 2 * r * π, where: r = </span>radius<span> and π = </span>3.14<span> 1) All you have to do is substitute in order to find the </span>radius<span> (r) of the </span>bike tire<span>, C = 2πr 82.896 = 2 * </span>3.14<span> * r 82.896 = 6.28 * r r = 82.896 / 6.28 r = 13.2. Thus, r = 13.2 which means that the </span>radius<span> of the circle (</span>bike tire<span>) is 13.2 </span>inches<span> </span>
