Answer:
b. 6.28 units
Step-by-step explanation:
The travel through 360° takes you around the full circumference of the circle. That circumference is ...
C = 2πr
Since this is a unit circle, the radius is 1, so the circumference is ...
C = 2π·1 = 2π ≈ 6.28 . . . units (counterclockwise)
Angles are generally considered to be positive in the counterclockwise direction, so the distance traveled is 6.28 units counterclockwise. Answer choice (a) has the correct number of units, but the direction is incorrect.
I'm not sure. But i think the answer is C
You can see that none of the lines are about to/ are intersecting
Let width be x m
perimeter = 2L + 2W
W = x and L = 4W - 7 = 4x - 7
so we have the equation
2(4x - 7) + 2x = 136
8x - 14 + 2x = 136
10x = 150
x = 15
So the width = 15m and the length = 4(15) -7 = 53 m. Answer
Answer:
Step-by-step explanation:
number of slices = 360 / 60 = 6
radius = 18 / 2 = 9 in
pizza area = (pi / 4) * d^2
= (pi / 4) * 18^2 = 254.5 in^2
area of one slice = 254.5 / 6 = 42.4 in^2
Answer: (x -4)^2 +(y -7)^2 = 36
Step-by-step explanation: The equation of a circle with radius r and center at (h, k) is ...
(x -h)^2 +(y -k)^2 = r^2
When the diameter is 12, the radius is 6 (half the diameter). Then for your center point, the equation is ...
(x -4)^2 +(y -7)^2 = 36
