C = -840
Isolate C by subtracting 900 on both sides:
C = 60-900
Which then gives u C = -840
Since the radius is 6 inches, the area is
squared inches.
Now, the full circle is a sector given by a 360° angle. So, the area of a 140° angle will be proportionate:

Solving for
, we have

Hello!
To find the volume of the prism you first have to find the volume of a cube
To do this you use the equation

V is volume
a is side length
Put in the values you know

Solve
V = 0.125
Now to find the volume of the prism you multiply the volume of one cube by the amount of cubes in the prism
0.125 * 8 = 1
The answer is 1 cubic inch
Hope this helps!

Answer:
Angle B = 106.6 degrees
Step-by-step explanation:
b^2= a^2+c^2-2*a*c*cosB
9*9 = 4*4 + 7*7 - 2*7*4*cosB
81= 16+49-56cosB Subtract 16 and 49 from both sides
16= -56cosB Divide by -56 on both sides.
cosB= -16/56 Take the arccosine of both sides
B=arccos(-16/56)
B= 106.6
