Answer:
7. 2355 m
8. 1570 km
9. 157 cm
10. 40.82 m
Step-by-step explanation:
The circumference of a circle is pi * diameter or 2 * pi * radius.
If you are given the diameter, just multiply it by pi, 3.14.
If you are given the radius, then multiply the radius by 2 and then by pi, 3.14.
7. d = 750 m
circumference = pi * d = 3.14 * 750 m = 2355 m
8. d = 500 km
circumference = pi * d = 3.14 * 500 km = 1570 km
9. r = 25 cm
circumference = 2(pi)r = 2 * 3.14 * 25 cm = 157 cm
10. r = 6.5 m
circumference = 2(pi)r = 2 * 3.14 * 6.5 m = 40.82 m
pi·18.6^2·123°/360° - 1/2·18.6^2·SIN(123°) = 226.3
Answer:
12 inches
Step-by-step explanation:
A square has 4 sides with the same length.
The perimeter of a square is the 4 times the length of one side.
perimeter = 4s
perimeter = 4 * 3 inches
perimeter = 12 inches
Answer: The answer is 5 but all of them are five but on the number line it’s going to the right with no fill in, it’s just a circle going to the right. Also it gives you a clue it says more than meaning greater than so it’s going this way > but the line is going this way 0———————-> on the number line with no black fill in.
