The base of a circular tank sits on a square slab whose length measures 3 metres. the diameter of the tank is 2.8 m. let the area of the slab not covered by the base of the tank

your answer is the frist one

hop i

1010: 3030

is it i think

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

noncoplanar points are points that do not lie on the same line.
