Our first step is to figure out what formulas are needed for diameter, circumference, and area of a circle.
Diameter is simply twice the size of the radius so:
2 * radius = 2 * 40 feet = 80 ft.
Circumference = 2 * pi * radius = 80 ft * pi
If we say that pi = 3.14, then:
circumference = 251.2 ft.
Area = pi * radius^2 = pi * 1600 ft^2
Once again, if we assert pi = 3.14, then:
area = 3.14 * 1600 ft^2 = 5024 ft^2.
Answer:
-12,-9,8,10,12,16
Step-by-step explanation:
Answer:
a = 540°
b= 180°
Step-by-step explanation:
a= pentagon has 5 sides which means 180 × 5= 540
b= 540÷5=180
Answer:
47/100
Step-by-step explanation:
47 = 0.47 = 47/100
3y ≥ 2x + 5
3 3
y ≥ ²/₃x + 1²/₃
3 ≥ ²/₃(2) + 1²/₃
3 ≥ 1¹/₃ + 1²/₃
3 ≥ 3
The answer is D.
