The surface area of a sphere is given by the formula
.. A = 4π*r^2
.. A = 4π*(1.25 in)^2 ≈ 20 in^2
The teacher threw you a circle and said “solve”. But seriously though, is there A statement above? Or if not then “ACB” would be 30 degrees.
The answer is A because you have to subtract the pink ribbon by the red ribbon.
