Step-by-step explanation:
let Rinus age be R
Anu's age is equal to 20+R and 6×R
20+R=6×R
20+R=6R
Collect like terms
20=6R-R
5R=20
Divide both sides by 5
R=20/5
R=4
Therefor Rinu is 4 years while Anu is 20+4 which is 24 years

Answer:
In order to answer this you would need to use this equation: <em>A = πr² </em> (See explanation)
Step-by-step explanation:
So, The circumference of the circle is 65n?
What you need to do is <em>A = πr² </em>
Let's divide 65n by Pi (65/3.14)
That equals 20.70n
Now we have the diameter of the circle. We need the radius for <em>A = πr² .</em>
We need to divide the diameter by two (20.70/2)
We now have the radius of the circle: 10.35n
Now we need to plug 10.35n in our Area equation :<em>A = π10.35² </em>
So now we multiply the Radius by Pi (π * 10.35)
This means that the area of our circle is: A = 32.49
Your answer Is 32.49n
