Answer:
B. 225 π sq. units
Step-by-step explanation:
the diameter of circle = √18²+24²
=√324+576=√900 = 30
the radius = ½×30=15
the area of circle =
π × 15² = π × 225 = 225 π sq. units
Answer:
21°
Step-by-step explanation:
set it up
7x-1+3x-9=180
combine like terms
10x-10=180
take the ten to the other side
10x=190
divide both sides by 10
x=19
plug x in
3(10)-9
30-9
21
(Incase you need it the other angle is 159°)
Idk this cause my teacher. Any teach
23 + 35 + A=180
58 + a =180
-58 -58
-------------------
A = 122 degrees
You simply divide, since it's a fraction. If you divide 14 b7 25, you get an answer of 0.56. :)
