The cirum ference of cylinder is 44cm and height is 7 cm find its curved surface area​

308cm

Step-by-step explanation: The formula to find the curved surface area of a cylinder is 2πr × h. The formula for curcufrence is 2πr.

So,

2πr (circumfrence)= 44cm.

Height= 7cm.

2πr × h = 44 x 7 = Curved surface area.

Curved surface area= 308cm

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
