The area of the sector (As) of a circle may be calculated by the formula,
As = (a / 360) x π x r²
where a is the measure of angle in degrees and r is the radius. Substituting the known values,
As = (18 / 360) x 3.14 x (4²) = 2.512
Thus, the area of the sector is approximately 2.512 squared units.
Answer:
22.5
Step-by-step explanation:
Because
180÷2=90
so that would mean
45÷2=22.5
the answer will be 9 each side because it has 5 sides so if you divide 45 by 5 sides you will get 9 as your anser pls give me good rating and a thank
26 is a part of the whole. the proportion should be set up:
(26/x) = (5/100) It's the overall enrollment that is being asked.
If you also need to solve: Cross multiply, 26(100) = 5x, 2600 = 5x, divide both sides by 5, 520 is the enrollment
