Circle O has a radius of 5 centimeters and central angle AOB with a measure of 60°. Describe in complete sentences how to find t
jeyben [28]

Answer:

We can use the formula for finding arc length given ccx central angle and radius.(insert formula below) We then substitute 5 in for r and and 60 for x. We multiply 2 pi times 5 which gives us 10. We then reduce the fraction of 60/360 to 1/6. We multiply 10 pi by 1/6 and that gives us

10 pi/6 or 5 pi/3

Step-by-step explanation:

We can use the formula

2\pi  \times r( \frac{x}{360} )

to find the arc length where r is the radius.

and x is the arc measure.

Plug it in for the numbers

2\pi \times 5( \frac{60}{360} )

Multiply 2 pi times 5=10 pi

10\pi( \frac{60}{360} )

Simplify 60/360 to 1/6

10\pi \times  \frac{1}{6}  =  \frac{10\pi}{6}

Reduce it to

\frac{5\pi}{3}

X^3 - y^3 = 218 where x and y are positive integers. Find x+y
finlep [7]

The value of x + y is 12

<h3>How to solve for x + y?</h3>

The equation is given as:

x^3 - y^3 = 218

Make x^3 the subject

x^3 = 218 + y^3

The next cubic expression greater than 218 is 343.

So, we assume

x^3 = 343

This gives

x = 7

Substitute x^3 = 343 in x^3 = 218 + y^3

343 = 218 + y^3

Evaluate the like terms

y^3 = 125

This gives

y = 5

So, we have:

x + y = 7 + 5

Evaluate

x + y = 12

Hence, the value of x + y is 12

Is that the whole question? It does not specify, so that means there is a 50/50 chance for either.
