Answer:
397.16 cm²
Step-by-step explanation:
Area of the circle = πr²
3.14 * 144 = 452.16
452.16 - (11 x 5 ) = area shaded region
452.16 - 55 = 397.16

Answer:
1. Substitute y = -3x +4 for y in the first equation
2. Combine like terms and isolate x
3. Substitute in x into the 2nd equation to get y
Step-by-step explanation:
1. Substitute y = -3x +4 for y in the first equation
2x- (-3x+4) = 6
2. Combine like terms
5x -4 = 6
5x -4 +4 = 6+4
5x=10 Divide by 5 to isolate x
5x/5 =10/5
x=2
3. Substitute in x into the 2nd equation to get y
y = -3x +4
y = -3(2) +4
y = -6+4
y=-2
(2,-2)

Answer:
F=73.74 degrees
Step-by-step explanation:
sin=opposite/hypotenuse
opp=24 hyp=25
sin(F)=24/25 (to find angle have to use inverse sin)
sin-1(24/25)=73.74
