Answer:
Part 7)
Part 8)
Step-by-step explanation:
Part 7) Find the length of AB
we know that
The<u><em> two tangent theorem</em></u> states that if we draw two lines from the same point which lies outside a circle, such that both lines are tangent to the circle, then their lengths are the same
so
In this problem, applying the two tangent theorem
AB=BC
substitute the given values
solve for x
Find the length of AB
substitute the value of x
Part 8) we know that
If CD is tangent to circle E at point C
then
Line segment CD is perpendicular to line segment EC (radius) and CDE is a right triangle
so
Applying the Pythagorean Theorem in the right triangle CDE
substitute the given values
solve for x
3 meters = 300 cm
300 cm + 35 cm = 335cm
Each cm is 10mm
So 335 cm = 3350 mm
It would be <span>6.6332495807108 and if you round that to the nearest hundredth, you’d get 6.63</span>
1.5 yards is the correct answer
54in=4ft 6in=1.5yd
First know how to get circumference of a circle
the formula is
c=2πr
radius is 1/2 the diameter
1/2*1/6 = 1/12
r= 1/12
π = 22/7
c= 2(22/7)(1/12)
c=11/21 yard
