PLEASE HELP WILL GIVE BRAINLIEST find the circumference of each circle round to the nearest tenth

7) 75.4 yd

8) 34.56 mi

6) 81.68 cm

Step-by-step explanation:

The formula of circumference is: circumference (C) = 2 * π * r

7) The radius = 12 yd

π = 3.14

We can solve for C:

C = 2πr

C = 2(3.14)(12 yd)

C = 75.4 yd

8) The radius = 5.5 mi

π = 3.14

Solve for C:

C = 2πr

C = 2(3.14)(5.5 mi)

C = 34.56 mi

6) The diameter is 26. The radius is one half of the diameter; so the radius is 13.

We can solve for C:

C = 2πr

C = 2(3.14)(13 cm)

C = 81.68 cm

Hope this helpsss <3

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
