Angle C is inscribed in circle O. AB is a diameter of circle O. What is the radius of circle O?

8.5 Units

Step-by-step explanation:

The radius of a circle is always half of the diameter. To find the length of AB, we can use Pythagorean's equation.

a² + b² = c²

(15)² + (8)² = c²

225 + 64 = c²

√289 = √c²

c = 17

This means that AB is 17 units. Now that we know the diameter, we only need to divide it in half to get the value of our radius.

17 ÷ 2 = 8.5 Units

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
