The area of the circle is 6,358.5cm²
<h3>Area of the circle</h3>
The formula for calculating the area of a circle is expressed as;
r is the radius = x + y
r = 25 + 20 = 45cm
Substitute the given parameters into the formula to have:
A = 3.14(45)²
A = 6,358.5cm²
Hence the area of the circle is 6,358.5cm²

Answer:
The most basic fact about triangles is that all the angles add up to a total of 180 degrees. The angle between the sides can be anything from greater than 0 to less than 180 degrees. The angles can't be 0 or 180 degrees, because the triangles would become straight lines.

Answer:
70 m
Step-by-step explanation:
AB makes a 30-60-90 triangle with the wall.
AC makes a 45-45-90 triangle with the wall.
In a 30-60-90 triangle, the short leg (opposite of the 30° angle) is half the hypotenuse.
In a 45-45-90 triangle, the legs are the same length.
So the distance between the left wall and the laser is 60/2 = 30 m.
The distance between the right wall and the laser is 40 m.
The total distance is therefore 70 m.
