Answer:
Formula for the area of a circle;
A = π[tex]r^{2}[/tex]
Where 'π' represents pi(22/7 or 3.14), and 'r' stands for the radius being squared.
But, we are given a diameter instead of a radius.
So to find the radius of the diameter we must find 1/2(half) of the diameter:
Diameter/2 = Radius
Plug in what we know:
D/2 = R
8/2 = R
4 = R, 4 is our radius.
Now we use this radius in our formula;
A = π[tex]r^{2}[/tex]
A = 3.14(4^2) ← (The symbol ' ^ ' means to the power of.)
A = 3.14(16)
A = 50.24 centimetres is the area for this circle.
