Given
Required :
The formula for the circumference of a circle:
When we substitute and simplify:
10*2=20
100 / 20 = 50
50^2 = 2500
5^2 = 25
2500 / 25 = 100
ANSWER = 100
2.2(5) - 4.33(1) >0
11 - 4.33 > 0
6.67 > 0
B)Yes
KMN = 90° (tangent perpendicular to radius)
Using Pythagoras Theorem,
√(8^2 + 6^2) = √(100) = 10
Therefore KN = 10km
6 the answer is number six
