Find the arc length on a circle with radius =4 inches and central angle of 30°
1 answer:
Answer:
Step-by-step explanation:
I'm assuming you're not doing the pre-calculus version of this equation where your angle is in radians. So we'll do the Geometry version which looks like this:
Our angle is 30 and our radius is 4, so we fill in accordingly:
(this is if you multiply in pi. We'll find the answer in terms of pi as well).
AL = and
AL = 2.09433 inches
In terms of pi, the answer would be
AL = inches

Answer:
1a. 8
1b. AB & BC
1c. AC
2. miles
3. NO
Step-by-step explanation:
1a. AC is your hypotenuse which is C² and BC is B², so we plug it in the equation.
A²+6²=10²
A²+36=100
A²=64
A=
A=8
1b. Legs are the two shorter sides, AB & BC, which are 6 & 8 respectively.
1c. The hypotenuse is the longest side AC
2. Make lines that make the graph for a triangle with a line. My graph is linked below. Then counts the points, AC=6, BC=4, then use the pythagorean therom.
6²+4²=X²
36+16=52
=X
3. 15²+17²=19²
514=361
not possible
so it is not a right triangle
