Question

find the height of a cylinder whose base radius is 7 cm find the total surface area is 1936 CM square ​

Answer 1

Answer:

h=37

Step-by-step explanation:

Total surface area of a cylinder=2πr(r+h)

=> 1936=2×22/7×7(r+h)

7and 7cancels out

1936=44(7+h)

1936/44=7+h

44-7=h

h=37

hope it helps:)

Answer 2

Step-by-step explanation:

Let height be 'h'

radius = 7 cm

Total surface area = 1936 CM sq

Total surface area =2π r (7 + h)

1936 = 2 * 22/7 * 7 (7 + h)

1936 * 1/2 * 7/22 * 1/7 = 7 + h

44 = 7+h

44 - 7 = h

h=7

height is 37 cm
