Circumference of the circle is given as = 220 feet
We have to find the diameter.
Circumference is found as = 2 * PI * r


r=35.03
Diameter is 2*radius
Diameter =
= 70.06
Hence, diameter of the circle is 70.06 feet.
Answer:
The area of the regular hexagon is 
Step-by-step explanation:
we know that
The area of a regular hexagon can be divided into 6 equilateral triangles
so
step 1
Find the area of one equilateral triangle

we have

----> is the apothem
substitute


step 2
Find the area of 6 equilateral triangles

Answer:
A D E
Step-by-step explanation:
A. In the second problem, the first fraction is less than the second fraction.
D. If you subtract a lesser number from a greater number, the answer is positive.
E. If you subtract a greater number from a lesser number, the answer is negative.
Okay, Jackie starts with 350 mailboxes, but has delivered to 150, so she only has to deliver to 200 more. She can deliver to 50 mailboxes per hour. So 200/50 = 4. The answer is 4 hours.
The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side; then:
15 + 27 = 42; 27 − 15 = 12. Therefore, third side must be less than
42 ft ant greater than 12 ft; so, possible lenghts for third side is given by the inequality: 12 < x < 42.
