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
Unit rate is often a useful means for comparing ratios and their associated rates when measured in different units. The unit rate allows us to compare varying sizes of quantities by examining the number of units of one quantity per one unit of the second quantity. This value of the ratio is the unit rate.
