Assuming that the center of each circle is at point C and D, then both have a radius of 7cm. We know that the formula for solving area of the circle is A=pi*r². Then we solve area of once circle multiplied by two to get the total area of the given circles. The solution is shown below: C1 area=3.1416*7² C1 area=153.9384 cm² Summation of the area of circle C and D is shown below: Sum area=2*153.9384 Sum area=307.8768cm²
