Answer: 181.46 square inches
Step-by-step explanation:
Area = pi ˣ r squared
Since the radius (half of diameter) is 7.6 inches, then it should equal to 181.46 square inches.
Answer: Find the value of X in triangles by subtracting known angle measurements from 180 degrees. Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle

Answer:
m<a = 77
m<b= 103
Step-by-step explanation:
m<a+m<b = 180(supplementary angles)
3x/8+50+x+31=180
3x/8+x+81=180
(3x+8x)/8=180-81
3x+8x=99*8
11x=792
x=792/11
x=72
now
m<a=3x/8+50
=(3*72)/8+50
=77
m<b=x+31
=72+31
=103
