Solutions
We know that <span>the mass of a tiger at a zoo is 235 kilograms. Randy's cat has a mass of 5,000 grams. To solve the problem we have to convert 235 kilograms into grams.
</span>235 kilograms = 235000 grams
<span>Randy's cat has a mass of 5,000 grams
</span>
Randy's cat = <span>5,000 grams
</span>
Tiger = <span>235000 grams
</span>
Our next step is to subtract 5000 from <span>235000 grams
</span>
235000 grams - <span>5000 grams = 230000
</span>
Answer = <span>230000 grams </span>
The formule is about area of a circle.

We need to solve the equation for x. Where x is the radius of the circle.
In order to solve it for x, we need isolate it for x on left side.
So, first we need to get rid pi from left side.
On dividing both sides by pi, we get


Taking square root on both sides, we get
