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

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
