Answer:
5 rad
Step-by-step explanation:
Recall that the length of an arc of circumference is given by the formula:
, where 
is the subtended angle [in radians] from the circumference's center.
Therefore in this case, you know the arc length (81.5 cm), and the radius (16.3 cm), and can solve for the angle using the above equation as shown below:
Answer:
The coordinates for the point on a circle of radius at an angle of are At the radius of the unit circle, 1, serves as the hypotenuse of a 30-60-90 degree right triangle, as shown in (Figure).
Step-by-step explanation:
Answer:
B. 14x^3+39x^2+18x+20
Step-by-step explanation:
Given polynomials are:
The product of given polynomials is:
14x^3+39x^2+18x+20
Hence, Option B is correct ..
If it is said that the range of the answer should be +/- 10% of the particular value, we have to find out the percentage of that particular value. Therefore 10% of 1.8 is,
1.8 * 10/100 = 0.18
If we add this value to the original value,
1.8+0.18 = 1.98
If we subtract this value from the original value,
<span>1.8-0.18 = 1.62
</span>
therefore the range will be,
from 1.62 to 1.98
