Answer:
b = 29.0, A = 123.9°, C = 20.1°
If the diameter is given in a problem, area is computed as
A = (π/4) × D<span>2 where </span><span>π is equal to 3.14</span>
<span>If D (diameter) of one circular table is 6 ft its Area is 28 sq ft.</span>
If D of another circular is 8 ft its Area is 50 sq ft.
<span>The difference between the areas of the two tables is, therefore (50-28) or 22 sq. ft.</span>
Answer:
115.56 but since you have to round to the nearest km is 116
Step-by-step explanation:
Implicit defferentation
remember that dy/dx y= dy/dx
so
take derivitive of both sides

solve for

minus 2x both sides

divide both sides by 2y


when is the slope equal to

solve for





find where the circle and this line intersects
substitute

for y




times both sides by


sqrt both sides, take positive and negative roots
x=+/-10
sub back




the points are (10,-24) and (-10,24)
Answer:
53
Step-by-step explanation:
24+16=40 40+37=77 77-24 = 53
