Hello,
√2(3√2+√18)=3*2+6=12
Answer A
Answer: about 450.52
Use Pythagorean Theorem to find the diameter of the circle. Divide the diameter by 2 to find the radius, and solve for the area of the circle (πr^2). Then, solve for the area of the triangle (bh/2). Subtract the area of the triangle from the area of the circle.
65+40÷83=1 which would be the least simplest way to solve it but sorry
