The lateral area is π r ℓ units² 
<span>The base is 20 feet across so the radius is 10 feet </span>
<span>Multiply 3.14 × 10 × 14 </span>
<span>3.14 × 10 = 31.4 </span>
<span>31.4 × 14 = 31.4 × 10 + 31.4 × 4 </span>
<span>= 314 + 120 + 4 + 1.6 </span>
<span>= 434 + 5.6 </span>
<span>= 439.6</span>

Answer:
Step-by-step explanation:
Let the horizontal distance is x
<u>Use tangent to solve this:</u>
- tan 30° = 6/x
- x = 6 / tan 30°
- x = 10.4 mi (rounded) 
 
        
             
        
        
        
Answer:
slope = -1.5
Step-by-step explanation:
A set of three or more points are said to be collinear if they all lie on the same straight line.
We have been given the following collinear set of points;
 P(0, 3), Q(2, 0), R(4, -3) 
This implies that P, Q, and R lie on the same line.
The slope of a line is defined as; (change in y)/(change in x)
Using the points P and Q, the slope of the line is calculated as;
(0-3)/(2-0) = -3/2 = -1.5
