Answer:
4 times 1 plus 3 equals 7
Step-by-step explanation:
Answer for question 1:
2 3/6 or 2 1/2 miles
Step-by-step explanation:
1/3 is 5/6 so you: 5/6 x 3=15/6. Then you turn the mixed number to a whole number: 15/6=2 and 3/6. You can also simplify it to 2 and 1/2.
Answer:
96
Step-by-step explanation:
IT IS CONVENTIONAL to let the letter s symbolize the length of an arc, which is called arc length. We say in geometry that an arc "subtends" an angle θ; literally, "stretches under."
Now the circumference of a circle is an arc length. And the ratio of the circumference to the diameter is the basis of radian measure. That ratio is the definition of π.
π = C
D .
Since D = 2r, then
π = C
2r
or,
C
r = 2π .
arc lengthThat ratio -- 2π -- of the circumference of a circle to the radius, is called the radian measure of 1 revolution, which are four right angles at the center. The circumference subtends those four right angles.
arc length
Radian measure of θ = s
r
Thus the radian measure is based on ratios -- numbers -- that are actually found in the circle. The radian measure is a real number that indicates the ratio of a curved line to a straight, of an arc to the radius. For, the ratio of s to r does determine a unique central angle θ.
