The circumference of an object is the total length of the line that forms the object. For a circle, the formula is:

C = 2 π r

We can see that in the formula, what is multiplied by 2 π is the radius (r).

Therefore the answer to this is

B. Radius

AB = 10 in; AD = 6 in A= 30sqrt3 in2 30 in2 60 in2

Ratling [72]

Answer: 30

Step-by-step explanation:

If we were to draw diagonal BD, then we would create two congruent triangles, and we could find the area of each using the formula $A=\frac{1}{2} ab \sin C$ .

However, since there are two triangles, we can double this, giving us $A=ab \sin C$ .

So, the area is $A=(10)(6)(\sin 30^{\circ})=\boxed{30}$

Solve each system of equation Y=-3x+5 5x-4y=-3

____ [38]

Y = -3x + 5
5x - 4y = -3

   5x - 4(-3x + 5) = -3
5x + 4(3x) - 4(5) = -3
   5x + 12x - 20 = -3
   17x - 20 = -3
   + 20 + 20
      17x = 17
   17    17
      x = 1
      y = -3x + 5
      y = -3(1) + 5
      y = -3 + 5
      y = 2
      (x, y) = (1, 2)
