Answer:

radius = 5

Step-by-step explanation:

Since the line is a tangent, that means the PT and OP are perpendicular (they make a right angle) Sooo, the triangle is a right triangle. Use Pythagorean Theorem to calculate or Pythagorean Triples for a shortcut (5, 12, 13)

r^2 + 12^2 = 13^2

r^2 + 144 = 169

Subtract 144

r^2 = 25

Squareroot both sides.

sqrt(r^2) = sqrt25

r = 5

The radius is 5.

Serggg [28]

Answer: 23.2 miles per hour

Step-by-step explanation:

He ran 100 meters in 9.63 seconds.

First convert the number of meters he ran to miles:

= 100 * 3.28

= 328 feet

= 328/5,280

= 0.062121212 miles

Convert the seconds to hours:

= 9.63 / 60

= ‭0.1605‬ minutes

= ‭0.1605‬/60

= ‭0.002675‬ hours

Speed in miles per hour is:

=  0.062121212 / ‭0.002675

= 23.22

= 23.2 miles per hour
