Answer:
Area for small square: 25 because 5x5 equals 25
Area for rectangle: 77 because 11x7 equals 77
Area for the irregular shape: 102 because you must add 25 and 77 together

I'm sorry if I'm wrong. Have a nice day! <3 (I'm currently learning myself but I'm 100% sure I'm right)
Answer:
its B
Step-by-step explanation: trust me but also you can graph it and it will show the points
Answer:
C = πd. where C is the circumference and d is the diameter of the circle. Using radius instead of diameter, the formula is: C = 2πr. where r is the radius of the circle.
Step-by-step explanation:
The arc length traveled by the needle is 7.0904
Step-by-step explanation:
<u></u>
<u>Step 1</u>
In the above question are given that
The speedometer needle in a car is 2.5 inches long
The needle sweeps out an arc of 130°.
Let r be the length of the speedometer needle,So
r=2.5
m∠C=130°
<u>Step 2</u>
The formula for determining the area of the sector is
A=*
Where,the central angle is m°
and The radius is r
Substituting the value of m and r from the step 1 in the below equation we get
A=*
A= 0.3611**6.5=7.0904
Hence the value of the Area of the sector is = 7.0904
<u></u>
<u>Step 3</u>
<u>So, the arc length traveled by the needle </u><u> 7.0904 </u><u />
