How to estimate the central angle in degree? </h3>
A unit circle by definition contains a radius of 1 unit.
We have to estimate the length of the arc subtended by an angle of 
radians.
arc length = radius 
angle
s = r
Where s be the arc length
r be the radius of the circle
be the angle measured in radians
arc length = 77cm
arc length = 77 7(3.14) / 2
arc length = 846.65922 cm
Therefore, the arc length of the circle exists 846.65922 cm.

Answer:
D. 28.26 in²
Step-by-step explanation:
Area of a circle= πr²
r= 3
π= 3.14
A= (3.14)(3)²
A= 28.26 in²
Step-by-step explanation:
f(x) = -12(8)^x
f(1) = -12 * 8¹
= -96
Answer:
c
Step-by-step explanation:
To find the maximum point, differentiate:
D' = -8p +160
Set to zero and solve for p:
D' = 0
⇒ -8p +160 = 0
⇒ 8p = 160
⇒ p = 20
Input p = 20 into the original equation to find D:
D = -4(20)² + 160(20) -310 = 1290
Therefore, the price is $20 and the maximum number of drills is 1,290
