63.62m²

Answer 2

pi r^2

Answer 3

In theory you could use 1/2 base x height because calculus proves these formulas pi r^2 and 1/2 base x height are related. You could imagine a circle full of rings. Unroll those rings and you get a triangle. Plug in the variables to the formula and you get 1/2 R x pi^2. Which would be equivalent to pi r^2

Answer 4

i dont remember typing that
