Answer:
below pls make me brainliest and like.
Step-by-step explanation:
d= 2.2v+\frac{v^2}{20}. to calculate breaking distance then breaks.
The measure of the central angle is 4 radians
<h3><u>
Solution:</u></h3>
Given that central angle of a circle intercepts an arc of length 28 centimeters
The radius of the circle is 7 centimeters
<em><u>To find: measure of the central angle in radians</u></em>
The arc length of circle when
is measured in radians is given as:

Where "s" is the arc length
"r" is the radius of circle
is the central angle in radians
Substituting the values in formula,

Thus the measure of the central angle is 4 radians
Answer:
330ft²
Step-by-step explanation:
Area of figure = Area of rectangle + Area of semicircle
= lb + pi r²/2
= 10 x 8 + 3.1 x 4 x 4/2 ( as 8 is diameter)
= 80 ft² + 248 ft²
= 328 ft² => 330ft²
