Answer:
Formula for the area of a circle;
A = π
Where 'π' represents pi(22/7 or 3.14), and 'r' stands for the radius being squared.
But, we are given a <u>diameter</u> instead of a <u>radius</u>.
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, <u>4 is our radius</u>.
Now we use this radius in our formula;
A = π
A = 3.14(4^2) ← (The symbol ' ^ ' means to the power of.)
A = 3.14(16)
A = <u>50.24 centimetres</u> is the area for this circle.
