The measure of a central angle ycz is 80 degrees. what is the sum of the areas of the two shadded sectors?

the sum of the areas of the two shaded sectors

step-by-step explanation:

see the attached figure to better understand the problem

we know that

the area of a circle is equal to

where

r is the radius of the circle

in this problem we have

substitute

remember that

subtends the complete circle of area equal to

so

by proportion

find the area of the two shaded sectors

it is 28 degrees colder in detroit than philadelphia.

step-by-step explanation:

what number adds to 21

-7 + ? = 21

-7 + 28 = 21

hope it

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
