A10 inch cookie cake is divided into 8 slices. what is the area of 3 slices

The area of 3 slices is  or approximate

Step-by-step explanation:

Find out the area of the cookie cake

The area of the circle (cookie cake) is

we have

----> the radius is half the diameter

substitute

Remember that the area of the complete cookie cake subtends a central angle of 360 degrees

If the cake is divided into 8 slices

then

The central angle of each slice is equal to

360/8=45°

The central angle of 3 slices is equal to

3(45°)=135°

By proportion

Find out the area of 3 slices

Let

x ----> the area of 3 slices

Simplify

----> exact value of the area of 3 slices

Find out the approximate value of the area of 3 slices

assume

substitute

use google you idiot omg you're so annoying

step-by-step explanation:

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
