Express the area of the circle in terms of diameter d.
Added by Eileen P.
Step 1
We know that the diameter (d) is twice the radius (r), so we can write: d = 2r Solving for r, we get: r = d/2 Substituting this value of r into the formula for the area, we get: A = π(d/2)^2 Simplifying, we get: A = πd^2/4 Show more…
