A circle has a circumference of 50.2450.24 units. What is the radius of the circle?

Mathematics

Roman55 [17]3 years ago

The formula for circumference is 2 x PI x r

Using the circumference we can find the radius:

50.24 = 2 x PI x r

Multiply 2 by PI:

2 x 3.14 = 6.28

50.24 = 6.28 x r

Divide both sides by 6.28:

R = 50.24 / 6.28

R = 8

The radius is 8 units.

Let x represent the worth of the professional basketball player's autograph a year ago. Since his autograph's worth increased by 40% now, $364 is 1.40x. 
 
                                      364 = 1.40x

Solving for x gives x = 260.

Thus, the autograph of the basketball player was worth only $260 last year.

7/12 divided by 2/5 I need help thanks and bye
Law Incorporation [45]

hey there!

7/12 divided by 2/5 is 7/30

first you have to find the reciprocal for 2 / 5 can do that by flipping 2 / 5 you'll then get 5 / 2 now the rest is simple all you have to do is multiply 7/12 by 2/5 so you multiply 7 by 2 and you get 14 that's your numerator 10 divide 12 by 5 and you'll get 60 so now you have 14 / 60 7 / 30 now you simplify and you get

I hope I helped please mark me brainliest

A regular hexagon has a radius of 20 in. what is the approximate area of the hexagon
soldier1979 [14.2K]

Remark

You need 2 facts to solve this 

1.   The area of a hexagon is 

     A = 3*(sqrt(3) ) * a^2/2 

     Just to make this clear, I'll put it in Latex

Area = (3*\sqrt3 a^2)/ 2

2. The second fact you need to know is that the radius = the length of the side a.

Givens

r = 20 in

a = r where a is the length of the side of a hexagon.

Formula Substitute and solve.

A = 3*(sqrt(3) * a^2 ) / 2

A = 3*(sqrt(3) * 20^2) / 2

A = 3*sqrt(3) * 400 / 2

A = 3*sqrt(3) * 200

A = 3*1.7321 * 200

A = 1039 square inches.
