The circumference of the circle is 10.36
The answer is c 10% of 89 is 8.9 so multiply by 3 you get 26.70
Answer:
divide 81 by pi and then by 2
Step-by-step explanation:
Answer:
A = 100 
Step-by-step explanation:
You have to use the area of a trapezoid formula:
A = 
(a + b)
Now, substitute the values of the height and the bases:
A = 
(10 + 15)
Finally, simplify the equation to solve for the area:
A = 4(25)
A = 100
Answer:
f(-3) = -2
f(-2.6) = -2
f(0.6) = 2.4
f(4.5) = 8.5
Step-by-step explanation:
(Whole question:
Evaluate the piecewise function for the given values.
Find f(-3), f(-2,6), f(0.6), and f(4.5) for f(x)={ -2 If x ≤ 0 4x. If 0 <x <1. x + 4. If x ≥ 1)
As the piecewise function shows, the function f(x) has the value of -2 for values of x lesser or equal than 0, has the value of 4x if the value of x is between 0 and 1, and has the value of x+4 for values of x greater or equal than 1.
So, for f(-3), the value of x is lesser than 0, so we have that f(-3) = -2
For f(-2.6), the value of x is lesser than 0, so we have that f(-3) = -2
For f(0.6), the value of x is between 0 and 1, so we have that f(0.6) = 4*0.6 = 2.4
For f(4.5), the value of x is greater than 1, so we have that f(4.5) = 4.5 + 4 = 8.5
