In the coordinate plane, the length of the line segment that connects points at (0, -1) and (-7, -2) is 7.07 units.
Answer:
So we know the formula to calculate the area of the circular sector:
S=(r^2*π*a)/306°=
(5^2*3.14*40°)/360°= (1000*3.14) /360=8.72cm^2 so the right alternative should be the first one ,A.
Step-by-step explanation:
r - radius of the circle
a - corner of the circular sector
S - surface
1feet = 12 incches so 12times by 9=108 inches
138,000/ 128,000 = 7.8125% Just divide new value into old value
