Charlie measured the circle-shaped part of a sun his sister drew on the chalkboard. the circumference of the circle is 94.2 cm. what is the diameter? (use 3.14 for pi)

30 cm

Step-by-step explanation:

The circumference (C) and diameter (d) are related by ...

... C = π·d

Then the diameter can be found from the circumference by dividing by π:

... C/π = d

... (94.2 cm)/3.14 = 30 cm

The diameter of Charlie's sister's sun is 30 cm.

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
