A=P(1+rt)
A/P=1+rt
A/P-1=rt
AP-P/Pr = t
A-1/r=t
The Solution.
The given equation is

Substituting 11 for x, we can get the value of y.

Hence, the value of y is 18.
Given diameter 2cm
Find the area of a circle
the formula for area of a circle
A = pi r^2
the diameter is the radius times two
so to find the radius given the diameter 2/2 = 1
radius is 1cm
pi is ~3.14
A = (3.14) * (1)^2
A = (3.14) * 1
A = 3.14
Hope this helps :)
