Problema Solution
Hugo ordered two circular pizzas, each with a diameter of 10 inches. Greg ordered one circular pizza with an area equal to the sum of the areas of hugos two pizza. What Was the diameter of gregs pizza?
Answer provided by our tutors
We assume the diameter of gregs pizza is X.
So
the area = pi*(x/2)^2 = 2*pi*(10/2)^2
x = 10*sqrt(2) = 14.14 inches
So the diameter of gregs pizza is 14.14 inches
