Work out the perimeter of a quarter-circle with radius 7cm. I will mark the person as brilliant

3.5π cm²

Step-by-step explanation:

let P represent the perimeter of a circle with radius 7

P = 2×π×r

  = 2×π×7

  = 14π

the perimeter of a quarter-circle with radius 7 = P÷4

= 14π÷4

= 3.5π

true

step-by-step explanation:

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
