Angle C is inscribed in circle O.
AB is a diameter of circle O.
What is the radius of circle O?
_units

5units

Step-by-step explanation:

The triangle inscribed in the circle is a right angled triangle with angle C being 90°.

The diameter of the circle AB is the hypotenuse of the triangle.

Before we can get the radius, we need to get the diameter AB using Pythagoras theorem.

|AB|² = |AC|²+|BC|²

|AB|² = 6²+8²

|AB|² = 36+64

|AB|² = 100

|AB| = √100

|AB| = 10

Diameter of the circle = 10units

Radius = diameter/2 = |AB|/2

Radius = 10/2

Radius = 5units

step-by-step explanation:

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
