Answer:
Step-by-step explanation:
The equation of a circle is: 
where ( h, k ) is the center and r is the radius. Therefore, the equation in this instance is .
Answer:
Step-by-step explanation:
s + r = 181
r = 119 + s
s + 119 + s = 181
2s + 119 = 181
2s = 181 - 119
2s = 62
s = 62/2
s = 31 <=== there are 31 senators
r = 119 + s
r = 119 + 31
r = 150 <=== there are 150 representatives
Answer: The spin of the wheel by the contestant is an illustration of a sine function whose equation is y = -1.25sin(0.8x + 0.25)
The shape at the top is a trapezoid with width 2 cm and lengths 4 and 8 cm.
Its area is
4+8
-------- 2 cm = 12 cm^2

The lower part consists of two congruent triangles. The area of a triangle is
A = (1/2)(b)(h). Here, A = (1/2) (4)(5.75) = 11.5, so the area of both triangles is 23 cm^2.
Thus, the total area is (12+23) cm^2, or 35 cm^2.
Volume of a rectangular prism is length x width x height.
Volume = 8 x 3 x 3 = 72 cubic feet
