circumference of a circle with a radius of 6 inches

Ali Soave · Accepted Answer

So here&#x27;s our circle with a radius of six to find the day of the conference, we would use pi times to radio, right? So since the Radius is, sex would say pi times two times six would be 12 and this would be approximately 37.7.

Okay, We&#x27;re gonna do problem number six, and we&#x27;re gonna find the exact circumference given a circle with a diameter of five. So if we know that the diameter hiss five we know that the circumference equals too high, R. But we also know that the diameter is equal to two are so we can change our formula for this. A conference to say that diameter times pi. So in this case, we can substitute and the five for the D And multiply that by pie. And this is our answer. Right here. It&#x27;s five pie and instant inches.

Georgiann Andersen · Answer

they were connected. Problem number four And the word&#x27;s gonna find the diameter of a circle when we have a circumference of 63 feet. So we have a circumference of 63 feet and we want to know what the diameter ISS. Okay, so we know that the formula for the sub conferences two pi r We also know that the diameter is equal to to our so we can actually change this formula to make it a little simpler. And it&#x27;s gonna be the diameter times pi. So if we know the circumference is 63 so we can say 63 equals the diameter times pi We can divide both sides by pi and our diameter is going to equal thio 20 0.5 feet.

so we know that that they&#x27;re circumference of a circle is equal to pi times to radio. So if we are told that the circumference is 28 pi, that&#x27;s gonna be equal to pi times to radio. Well, there is. We can divide both sides by pi and that cancels that out is to cancel out and that means to radio equals 28. We can divide both sides by two divided by two these cancel out and radius is equal to 14.

Ali Soave · Answer

So to find the circumference, we need to find what portion of the circumference R F G is when we can use that to find the total circumference of the circle. So we know about our F G. This 76 degrees out of 360 degrees that times whatever the circumference is, is equal to arc length, which is 7.5. So it were to find the value of C. Then let&#x27;s multiply your sides times 3 60 over 76. Are you 60 over 76? These cancel out leaving us with just see, and when we multiply this right side, we get about 35.53

Okay, this is problem number 10 and we&#x27;re going to try and find the radius. A circle are what we know is the are quaint of l m of Arc. Elham is 38 0.95 centimeters and we know that the major of Arc Elem is 260 degrees And we know that the formula of the arc length of arc LM will equal the measure of arc lm all over 360 degrees times two pi r So we know they are. Klink, this 38 0.95 we know the measure is 262 groupies over 360 multiplied by two pi r Yeah, so we can, um, simplify this a little bit and that&#x27;s gonna be 38.95. We&#x27;re gonna take the two pi times 2 to 6 CSI and then divide by the 360 simplifying that so it&#x27;s gonna end up being 13 over nine pi r. So now we can take and we can multiply both sides by the nine and then divide by the 13 pie and that&#x27;s gonna equal r r. When you go ahead and do the calculation of that, you&#x27;re gonna end up with the radius is going to equal 8.58 centimeters
