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

0.02040816326

whole number data type

step-by-step explanation:

as whole number type represents whole number

like 1, 2 ,3, 4

in other words the whole numbers are those numbers which cannot be written infraction.

since we can take days as a whole number i.e 1 day 2 day and we cannot write 1.2 day hence we will use whole number data type
