Answer:

aₙ= 6n +1

Step-by-step explanation:

Second term a₂= 13

Common difference d= 6

Then first term

a₁= 13 -6= 7

nth term:

aₙ= a₁ + (n-1)d
aₙ= 7 + (n-1)*6= 7+6n -6 = 6n +1
aₙ= 6n +1

A circular field has a diameter of 50 yards. If a fence needs to be built to go around the field, how many yards of fencing are

Xelga [282]

Answer:

Step-by-step explanation:

A fence is needed for the circular field.

Circumference is basically perimeter but for circles.

Knowing this information, we can use the formula for circumference.

C = $\pi$ d

C = (3.14)(50)

C = 157

hope it helps :)
