Rational numbers are numbers that can be turned into fractions. So A, C, D, E, F, G, H, and I are rational numbers
Answer:
Radius = r = 7.5
Diameter = d = 15
Circumference = C = 15π
Step-by-step explanation:
We are given the image of a circle with a straight line passing through the center of the circle and touching its edges. Such a line is known as the diameter of the circle. From the image we can see the length of the diameter of the circle is d = 15 units.
Radius is define as half of the diameter. Since the diameter is 15 units, the radius of the given circle will be half of 15 which is r = 7.5 units.
Circumference of the circle = C = 2πr
Using the value of radius(r), we can write the circumference as:
C = 2π(7.5) = 15π
5 km = 5000 meters
66 minutes = 3960 seconds
Meters per second = 5000/3960 = 1.26
The answer is A.1.26
