Question

A cylindrical tank has a capacity of 3080 cm . If it's depth is 20 cm , find it's diameter

Answer 1

Answer:volume of a tank= 3080 cm

vol. of a cylinder=pie r²h

3080= 22/7 x r²x 20

3080/20=22/7r²

154x7/22=r²

49=r²

r=√49

r=7 cm

diameter= 2x radius

diameter= 2x7

diameter=14 cm

hope it helps u

Answer 2

here is your answer ⤵️

Given :-

✴️ capacity =3080cm³

✴️ depth = 20cm

Now,,

Capacity of cylinder = volume of cylinder

➡️ Volume of cylinder = πr²h

➡️ 3080cm³ = 22/7 ×r²×20cm.

➡️ r² = 49cm

➡️ r = 7cm

➡️ diameter = 2 × radius

➡️ diameter = 2×7 =14 cm

➡️ hence, 14cm is the diameter of the cylinder.
