Answer:
36 pi cm^2
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
12 pi = 2 * pi *r
Divide each side by 2 pi
12 pi /2 pi = 2 * pi *r
6 = r
The area of a circle is given by
A = pi r^2
A = pi (6)^2
A = 36 pi
Function 1
rate of change = (80-100)/(2-1) = -20
y = -20x + 120
function 2
y = -18x + 120
rate of change = -18
answer
function 2 shows a greater rate of change

Answer:
The answer is 7.2
Step-by-step explanation:
Answer:
Volume: 105 cubic centimeters
Mass of doorstop: 924 grams
Step-by-step explanation:
First, you need to find the area of the triangular base of the prism. The area of the triangle is bh/2=10*6/2=30 square centimeters. Multiplying this by the height of the doorstop of 3.5, you get a total volume of 105 cubic centimeters. Since each cubic centimeter weighs 8.8 grams, the whole thing weighs 105*8.8=924 grams. Hope this helps!
