Question

the volume, lateral (curved) surface area and total surface area of the cylinder who
dimensions are:
(a) radius of base = 7 cm and height = 25 cm
(b) radius of base = 11 cm and height -35 cm
(c) radius of base = 6.8 cm and height = 9.5 cm
indir dinmeter 2 cm and height 30 cm. ​

Answer 1

Step-by-step explanation:

(a) solu -

volume of cylinder =πr²h

=22×7×7×25÷7

=3850cm³

curved surface area of cylinder=2πrh

=2×22×7×25÷7

=1100cm²

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

=2×22×7(25+7)÷7

=1408cm²
