V= pi Times r squared times h
First divide both sides by pi and h
V / pi h = r squared
Square root both sides.
The square root of v /pi times h = r
Area of entire trapezoid = <span>((sum of the bases) ÷ 2) • height
Trapezoid Area = (51 / 2) * 26
</span><span>Trapezoid Area = 663
UN-shaded triangle area = .5 * base * height
</span><span>UN-shaded triangle area = .5 * 23 * 26
</span><span>UN-shaded triangle area = 299
SHADED Trapezoid Area = 663 -299
</span><span>SHADED Trapezoid Area = 364

Answer:
b
Step-by-step explanation:
polygons is a plane figure that is described by a finite number of straight line segments connected to form a closed polygonal chain or polygonal circuit
Let $k = the monthly base fee.
The variable cost is $0.30 per minute.
Let
C = total cost in a month
x = minutes used
September:
x = 120 minutes
C = $50
Therefore
k + (0.30)(120) = 50
k + 36 = 50
k = $14
October:
x = 165 minutes
The cost is
C = 14 + (0.3)(165)
C = $63.5
Answer: $63.50
