The area of the circle is 706. 5 square units
<h3>What is the area?</h3>
The formula for area of a circle is expressed as;
Area = πr^2
From the information given ,we have that the radius of the circle is 15
Now, let's substitute the value of the radius into the formula;
Area = 3. 14 × 15^2
Area = 3. 14 × 15 × 15
Find the square
Area = 3. 14 × 225
Multiply through
Area = 706. 5 square units
Thus, the area of the circle is 706. 5 square units

Answer:
135°
Step-by-step explanation:
Since it's a right triangle, one angle will be 90° and the other given one is 45°. The total degrees in a triangle is 180 therefore ∠CAB is 45°.
Because ∠CAB is supplementary to ∠CAD, you have to subtract 180° -- since it's a straight line -- with 45°.
This gives you 135°
You can determine if a number is rational if it can be represented as a terminating or repeated decimal, but if it can not, then the number is irrational.
