Step-by-step explanation:
The Formula to find the Area of a circle using the radius is:
r = 8
So:
And you get about 201.06193
So, the area of a circle with a radius of 8 is about 201.06
Hope this Helps :)
When you divide fractions, you change each to its reciprocal, then you look multiply them. Using reciprocals helps you easily solve the problem.
add 4 each time
the nth term is a_n or f(n)
the next term after that is a_{n+1} or f(n+1)
so each term is 4 more than previous
basically
a_{n+1}=4+a_n or
f(n+1)=4+f(n)
