★ Given -:
Diameter of base of right circular cylinder = 35 m
height = 21 m
★ To find -:
Curved surface area
★ Solution -:
We know that ,
→ curved surface area of right circular cylinder = 2πrh
Diameter = 2 × radius
_______________________________________
35 = 2 × radius
radius = 35/2
→ radius = 17.5 m
_______________________________________
by putting the values in the formula
π = 22/7
★ Additional Information -:
Total surface area of cylinder =
2πr (r + h)
where ,
r is radius .
h is height .

As we know,
Curved surface area of right circular cylinder = 2πrh
Diameter = 2 × radius
35 = 2 × radius
radius = 35/2
☞ radius = 17.5 m
After putting their values in the formula
π = 22/7
=
