How do you find the arc length of a partial circle

1 answer:

8 0

A circle is 360° all the way around; therefore, if you divide an arc's degree measure by 360°, you find the fraction of the circle's circumference that the arc makes up. Then, if you multiply the length all the way around the circle (the circle's circumference) by that fraction, you get the length along the arc.

If the largest angle of a triangle is 120 degrees and it is included between sides of 1.5 and 0.5, what is the largest side of t

Amanda [17]

C²=a²+b²-2·a·b·cos(C)

c²=(1.5)² + (0.5) -2 ·(l·5) ·(0.5) ·cos(120°)

c²= 3.25

c= √3.25

c=1.802775638

To nearest tenth, c=1.8

The ratio of the areas is the ratio of the squares of the sides ( which is 10:15 or 2:3) so the answer is
2^2 : 3^2 = 4:9.

The ratio of the perimeters = ratio of corresponding side = 2:3.

Mumz [18]

Answer: -43.3

Step-by-step explanation:

We will use the order of operations, sometimes called PEMDAS. <em>See attached for more information on this subject</em>.

Given:

8.7 - (1 + 3)³ + 6 · 2

Simplify parentheses:

8.7 - (4)³ + 6 · 2

Raise to the power of three:

8.7 - 64 + 6 · 2

Multiply:

8.7 - 64 + 12

Subtract:

-55.3 + 12

Add:

-43.3
