​

Answer 1

Step-by-step explanation:

There is an mistake in question

reason - VOLUME ALWAYS HAVE CUBE IN ITS UNIT but in the question it is square

Answer 2

Find the height of a cylinder whose volume is 17600cm³ and base radius is 20cm.

$\huge{\textsf{\textbf{\color{purple}{Answer:-}}}}$

• Base radius = 20cm
• Volume given = 17600cm³
• Height = ?
• Volume formula of a cylinder = πr²h

==> 17600cm³ = $\frac{22}{7}×(20cm)×(20cm)×h$

==> 17600cm³ = $\frac{22}{7}×(400cm)×h$

==> 17600cm³ = $\frac{8800}{7}×h$

==> 17600cm³ × 7 = 8800 × h

==> 123,200 = 8800 × h

==> $\frac{\cancel1\cancel2\cancel3\cancel2\cancel0\cancel0}{\cancel8\cancel8\cancel0\cancel0}$=h

==> Height = 14cm

Therefore, the height of a cylinder whose volume is 17600cm³ and base radius is 20cm is 14cm.
