Me i need the right answer only find the circumference and area of a circle with a diameter of 14 inches. leave your answers in terms of pi. a) c = 14π; a = 49π b) c = 7π; a = 28π c) c = 14π; a = 28π d) c = 7π; a = 49π

Alright. Let's start with Circumference.

The formula for that is 2piR.

Radius of circle is half of diameter. 14/2=7

Plug it in, 2*pi*7

Simplify, answer is 14 pi

Area, formula is pi(R*R) (Sorry can't do squared)

Taking from before, pi*49

Simplify, it's 49 pi

Total: it's C=14 pi, A= 49 pi, or choice A

Hope this helped!

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

the correct answer is $7.38
