Drag and drop an answer to each box to correctly complete the derivation of a formula for the area of a sector of
a circle.
Suppose a sector of a circle with radius r has a central angle of 0. Since a sector is a fraction of a full
circle, the ratio of a sector's area A to the circle's area is equal to the ratio of the central angle to the
measure of a
rotation of the circle. A full rotation of a circle is 21 radians. This
proportion can be written as 4 = 1
Multiply both sides by arra and simplify to get
where
is the measure of the central angle of the sector and r is the radius of the
circle.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

answer:

it is 28 degrees colder in detroit than philadelphia.

step-by-step explanation:

what number adds to 21  

-7 + ? = 21

-7 + 28 = 21
