Answer:
59
Step-by-step explanation:
If we convert from degrees into radians, we can use the formula
, where s is the arc length, r is the radius and θ is the angle in radians.
To convert from degrees to radians, we multiply by 
So
is our angle in radians, and we have the radius - we can now plug in these two values into our equation.

Y-1=-4(X-4) is the equation
By definition, the volume of a cone is given by:

Where,
r: cone circular base radius
h: height of the cone
Substituting values we have:

Rewriting the equation we have:


Answer:
An expression that represents the volume of the cone, in cubic units is:

Note: rewrite the options again.
Answer:
x= -13, y= -7
Step-by-step explanation:
a) | -21 -17| = | - 38 | = 38
b) | 39 - 26 | = | 13 | = 13
c) | -17 -79 | = | - 96 | = 96
d) | -9+25 |= | 16 | = 16
e) | -21 -61 |= | - 82 | = 82
f) | 61-74 |= | - 13 | = 13
g) | -31 -79 |= | - 110 | = 110
h) | -12 +55 | =| 43 | = 43
