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 :)
x to the second power over 6=42. X=252
If f(x) = 3x - 12 and x = 9
then substitute 9 in place of x
f(9) = 3(9) - 12
f(9) = 27 - 12
f(9) = 15
