Question

pls solve this pls pls​

Answer 1

Answer:

Given that

Height of water filled in cylinder = 7cm

radius of base = 4 cm

To find:

Volume of water upto filled

We know that

Volume of water in cylinder = πr²h

= π×4²×7

π = 22/7

= 22/7×4²×7

= 22×4²

= 352 cm³

${\mathsf{\boxed{volume \: of water \: in \: cylinder =352 {cm}^{3} }}}$

Answer 2

Answer:

$height \: of \: water \: filled \: in \: cylinder = 7cm \\ radius \: of \: base = 10cm \\ csa \: of \: the \: cylinder = \ \: 2 \pi r h \\ = 2 \times \frac{22}{7} \times 10 \times 7cm \: sq. \\ = 2 \times 22 \times 10cm \: sq. \\ = 440cm \: sq.$
