The correct answer is

A. 50.24

B. 16

C. 50.24 , 16 ,803.84


Explain


A. Area = πr^2 = 3.14(4)^2= 50.24

B. Volume = area x height = 50.24 x 16 = 803 . 84 cubic cm


So for part c the answer are 50.24 , 16 , 803.84


Hopefully this help you :D

I WILL GIVE BRAINLEST FOR THE CORRECT ANSWER!
pentagon [3]

Answer:

A) -4

B) 4 units apart

C) no values of x

Step-by-step explanation:

1) slope of m: (3-2)/(10-8) = ½

m(x) = ½x + c

2 = ½(8) + c

c = -2

m(x) = ½x - 2

m(16) = 6

h(4) = (4-2)²/2 = 4/2 = 2

h(4)-m(16) = 2-6 = -4

B) y-intercept of:

*h(x) = ½(0-2)² = 2

*m(x) = -2

from the equation found before

2 - (-2) = 4 units apart

C) m(x) = (x-4)/2

m(x) > h(x)

(x-4)/2 > ½(x-2)²

x-4 > x²-4x+4

x²-5x+8 < 0

(x - 2.5)² + 1.75 < 0

Never negative
