Answer:

450 cm

Step-by-step explanation:

12 degrees is 1/30 of the circumference because there are 360 degrees in a circle.

The minor arc length of 15 is in the same ratio to the circumference as  the 2 angles , so the circumference = 30 * 15 - 450 cm.

Answer:

B = 450 cm

Step-by-step explanation:

Length of arc = theta/360 * 2 * pi * r

We know the length of the arc = 15, theta = 12

Substitute these values in

15 = 12/360 * 2 * pi * r

15 = 1/30 * 2 * pi * r

Solve for r

15 = 1/15 * pi * r

15*15 = pi * r

225/pi = r

Circumference = 2* pi * r

Circumference = 2 * pi * 225/pi

Circumference = 2 * 225

Circumference = 450 cm

Each leg of a 45-45-90 triangle has a length of 6 units. What is the length of its hypotenuse?
andreyandreev [35.5K]
Use the Pythagorean theorem:
(\hbox{one leg})^2+(\hbox{the other leg})^2=(\hbox{hypotenuse})^2 \\
6^2+6^2=x^2 \\
6^2 \times 2=x^2 \\
\sqrt{6^2 \times 2}=x \\ \sqrt{6^2} \times \sqrt{2}=x \\ 6\sqrt{2}=x

 
The length of the hypotenuse is 6√2 units.

Evalute the expression. 80 + (8x4) divided by 2
dexar [7]

Answer:

If you meant [80 + (8*4) ]/2,  then  [80 + (8*4) ]/2=56

or if you meant 80 +  [ 8*4 /  2], then 80 +  [ 8*4 /  2] = 96

Step-by-step explanation:

Evalute the expression. 80 + (8x4) divided by 2

so do you mean

the whole expression 80 + (8x4)   is  over  2 ?

If so then:

evaluate  8x4  =  8 * 4 = 32.

so   we have 80 + (8x4)   is  over  2  =  (80 + 32)/2 = 112/2 = 56

If you meant  80 +  [ 8*4 /  2]

then  80 +  [ 8*4 /  2] = 80 + 8*2 = 80 + 16 = 96
