Answer:
18.8 feet, 59.1 feet to the nearest tenth
Step-by-step explanation:
The diameter is the line drawn that divides the circle into two while the circumference is the perimeter of the circle. Both are a measure of the radius of the circle.
The diameter D = 2r where r is the radius of the circle
The circumference = 2Πr = ΠD where Π = 22/7
Given that the circular fountain has a radius of 9.4 feet
Its diameter = 2 × 9.4 feet = 18.8 feet
The circumference = 22/7 × 18.8 feet
=59.09 feet
≈ 59.1 feet to the nearest tenth
Answer:
38+31+43+x=180
Step 1: Simplify both sides of the equation.
38+31+43+x=180
(x)+(38+31+43)=180(Combine Like Terms)
x+112=180
Step 2: Subtract 112 from both sides.
x+112−112=180−112
x=68
Step-by-step explanation:
Answer:
(B)Use the slope formula to prove the slopes of the diagonals are opposite reciprocals.
Step-by-step explanation:
Two lines are perpendicular if the product of their slope is -1. That is, the slope of one is the opposite reciprocal of the other.
Mathematically, if their slopes are 
<u>Therefore, the correct option is B.</u>
