Answer:
<h2>The arc length is 4 cm to the nearest cm</h2>
Step-by-step explanation:
The diagram is not given in this question, but we can proceed anyways.
from the problem statement we can observe that the radius of the arc is same as the width of the door
a. the radius is 4.2 cm
b. the length of the arc given that the central angle is 25° can be gotten using the formula stated bellow
arc length = 2 π r *(∅/360)
substituting we have
arc length = 2*3.142*(225/360)
arc length= 6.284*0.625
arc length=3.92 cm
<h2>Approximately the arc length is 4 cm</h2>
The expressions are equivalent.
The third expression is wrong
Answer:
12
Step-by-step explanation:
54 / 3 =18
18 x 40 minutes = 720
720 / 60= 12
12 hours
Answer:
4x^3+2x^2=2
We move all terms to the left:
4x^3+2x^2-(2)=0
