Circumference of a circle:

A circle has a radius of 11 yd. What is its circumference?

Use 3.14 for π, and do not round your answer. Be sure to include the correct unit in your answer.

69.08 yards

Step-by-step explanation:

Circumference = 2pi×r

= 2×3.14×11

= 69.08 yd.

if x = 1, then the answer is 3.5

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
