Question

find the height of the solid circular cylinder of total surface area 660 cm^2 and radius 5 cm​

Answer 1

Step-by-step explanation:

660=2×22/7×5(h+5)

(660×7)/(22×2)=5h+25

105=5h+25

105-25=5h

80=5h

h=16cm

Answer 2

Answer:

Radius=5 cm

total surface area=660cm^2

As we know, Total surface area of cylinder=2πr(r+h)

660 =2×π×5×(5+h)

After solving this,we get:-

21=5+h

h=21-5

h=16 cm
