Answer:
A = 64 pi
Step-by-step explanation:
The circumference can be found by
C = 2 * pi *r
16 pi = 2 * pi *r
Divide each side by 2 pi
16 pi/ 2 pi = 2 * pi *r/ 2 pi
8 =r
The radius is 8
To find the area
A = pi r^2
A - pi (8)^2
A = 64 pi
Answer:
value x proves this parallelogram is a rhombus.
Answer: the area is 20 square centimeters.
Step-by-step explanation:
The area of an arc of angle x in a circle of radius r is:
A = (x/3.14)*3.14*r^2 = x*r^2
here we have x = (4/5)*3.14 and r = 5cm
Then the area is:
A = (4/5)*(5cm)^2 = 20cm^2
Answer: (b)
x g(x)
1 -16
2 -12
3 -8
If g(x) is 4*f(x), then we can find g(x) by multiplying 4 by x-5
g(x) = 4(x-5)
= 4x-20
Now we can plug in 1,2, and 3 for x to see which table makes sense.
g(1) = 4(1) - 20
= -16
g(2) = 4(2) - 20
= -12
g(3) = 4(3) - 20
= -8
hope this helps
