If the circumference of a circle is 84.5 ft, find the radius.

Answers

Answer 1

Answer:

13.448, rounded off: 13.5 ft

Step-by-step explanation:

[tex]r=\frac{C}{2\pi }[/tex]

Where r = radius, C = circumference.

[tex]r=\frac{84.5}{2\pi } =13.448[/tex] = 13.5 ft

Answer 2

Answer:

r = 13.5 ft

Step-by-step explanation:

The circumference of a circle of radius r is C = 2(pi)r.

Here, C = 84.5 ft = 2(pi) r, or

          C = 84.5 ft = 6.28r

Dividing both sides by 6.28 results in the value of r:

r = 84.5 ft / 6.28 = 13.5 ft

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

We have,

Dave and 6 friends went to dinner.

math question, evaluation ​

Answers

Answer:

P = 131 degrees

Step-by-step explanation:

We know that the sum of the interior angles of a triangle is 180 degrees

The exterior angles shown form a straight line with the corresponding interior angle

So the two interior angles can be calculated

The sum of two angles on a straight line is 180 degrees

By subtracting the exterior angles from 180, we can get the two interior angles which we can add to the angle at P to give 180

Thus;

P + (180-162) + (180-149) = 180

P + 18 + 31 = 180

P = 180-31-18

P = 131

Answer:

Explanation:
To determine the answer, you’d first want to identify the hypotenuse. The hypotenuse of a triangle is the side opposite of the right angle. Therefore, the hypotenuse would be LK, so that can’t be the correct answer.
JK is opposite of L, making it the opposite leg.
This leaves JL as the adjacent leg, since it is not the hypotenuse and it is touching L.
