The large clock below hangs in Isaac's living room. If the radius of this clock is 3.5 feet, what is its circumference? Round your answer to the nearest tenth.

22.0

Step-by-step explanation:

knowing the radius is 3.5 -

and the formula for the circumfrence -

2 pi r

we can then use the radius -

2 * 3.14 * 3.5

which is 21.98 -

rounding to 22.0

hope this helps!!

22.0

Step-by-step explanation:

to find the circumference of a circle you have to have the diameter, double the radius, and multiply it by pi or 3.14

can you put the picture up?

step-by-step explanation:

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
