A graphing calculator is recommended. A grain silo consists of a cylindrical main section and a hemispherical roof. If the total
eimsori [14]

Answer:

11.28 ft

Step-by-step explanation:

The volume of a cylinder can be written as;

Volume V1 = πr^2 h

The volume of an hemisphere can be written as;

Volume V2 = (2/3)πr^3

The total volume of the silo is;

V = V1 + V2

V = πr^2 h + (2/3)πr^3

Given;

Volume of silo V= 15000 ft^3

Height of cylinder part h = 30 ft

Substituting the values;

V = πr^2 h + (2/3)πr^3

15000 = 30πr^2 + (2/3)πr^3

15000/π = 30r^2 + (2/3)r^3

2r^3 + 90r^2 - (15000×3/π) = 0

Solving the equation, we have;

r = 11.28 ft or -15.61 ft or -40.67 ft

Since the radius cannot be negative;

Radius r = 11.28 ft

Theorem: The segment joining the midpoints of two sides of a triangle is parallel to the third side and half its length.
Elina [12.6K]

Answer:

Step-by-step explanation:

Statement Reason:

1) The coordinates of point D are (4, 5) and coordinates of point E are (5, 3) By the midpoint formula

2) Length of segment DE is Square root of 5 and length of segment AC is 2 multiplied by the square root of 5 By the distance formula

3) Segment DE is half the length of segment AC By substitution

4) Slope of segment DE is -2 and slope of segment AC is -2 by the slope formula

5) Segment DE is parallel to segment AC Slopes of parallel lines are equal...
