Answer:

A) 4.5 cm

Step-by-step explanation:

Given: Circumference of the circle = 28.3 cm

Here we are asked to find the radius "r".

2.π.r = 28.3

The value of π = 3.14

2*3.14.r = 28.3

6.28r = 28.3

Dividing both sides by 6.28, we get

r = 28.3/6.28

r = 4.5 cm.

The radius of the circle r = 4.5 cm

Answer: A) 4.5 cm

Thank you.

If f(x) = x2 and g(x) = x + 6, find g(f(0)).
Pachacha [2.7K]
Hi friend,

f(x) = x²
g(x) = x+6

f(0) = 0² =0

g ( f(0) ) = f(0) +6
= 0+6 = 6

Hope this helps you!

If the volume of the pyramid shown is 360 inches cubed, what is its height?
GenaCL600 [577]
<h3>Answer: 9 inches (choice D)</h3>

Work Shown:

V = volume of pyramid

V = (1/3)*(area of base)*(height)

V = (1/3)*(12*10)*h

V = (1/3)*120h

V = 40h

Set this equal to the given pyramid volume 360 cubic inches and solve for h

40h = 360

h = 360/40

h = 9

Please help and solve for x! (: thank you in advance.
Vera_Pavlovna [14]
First look at the given numbers, especially 123 degrees which if you add up the other side it equals 180 degrees so:
180-123= 57 
Ok now you know two sides of the triangle and you know that all the 3 sides add up to 360 degrees so:
57+75= 132
180-132= 48
