Answer:
Area of plane surface of cylinder = 2772 sq.cm.
Step-by-step explanation:
Let r be the radius and h be the height of the cylinder.
Curved Surface Area = 1848 sq.cm
2πrh = 1848
2××rh = 1848
rh = 1848 × ×
rh = 294
Sum of radius and height = 35
r + h = 35 --- (1)
Now,
r - h =
=
=
=
= 7
r - h = 7 --- (2)
Adding (1) and (2),
2r = 42
r = 21 cm.
Area of the plane surface = 2 × π
= 2 × × 21 × 21
= 2772 sq.cm.
