81 degrees
1 degree = 2 pi / 360
81 degrees = 162 pi / 360
=9 pi / 20
L (arc) = radius x angle
= 10 x 9 pi / 20
90 pi /20
9/2 pi : D
The answer is D
Answer:
r = 8
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
16 pi = 2 * pi r
Divide each side by 2 pi
16 pi /2 pi = 2 pi r / 2 pi
8 = r
4.7244m
convert feet to inches using 1 foot = 12 inches
15.5 feet = 15.5 × 12 = 186 inches
multiply this by 2.54 to convert to cm
186 inches = 186 × 2.54 = 472.44 cm
now 1m = 100cm
divide 472.44 by 100 to convert to m
472.44 ÷ 100 =4.7244m
Answer: B
Step-by-step explanation:
First, you have to find how many friends are playing. This can be found in the equation 5-3. Now you multiply by six to find the cost. If you chose C, that would be incorrect, because the () you would mltilply first (30) and then subtract 3 (27). You can also think of it as finding the cost of how much all of them want to play by using the distributive property, leaving you with 30 - 18, and subtract from there to get 12.
Answer:
x = -3
Step-by-step explanation:
The line parallel to x=8 is another vertical line:
x = constant
To make it go through a point with an x-coordinate of -3, the constant must be -3.
Your line is ...
x = -3
