Answer:  257.143 square centimeter (approx)

Step-by-step explanation:

Here, Three plates are stored in an L-shaped drawer, as shown so that they fit snuggly inside, with no spaces between the edges of the drawer and the plates.

Therefore,

Total area of L- shaped drawer which is not covered by these plates = Total covered area of the L-shaped drawer - Total area of three plates.

Since, the total area of L-shaped drawer= area of square of side 20 cm+ area of rectangle of length 40 and breadth 20.   ( by the given diagram)

Thus,  the total area of L-shaped drawer= 20^2+40\times 20

= 400+800

=1200 square cm

Here, the shape of plates are circular and having the radius of 10 cm. ( by the given diagram)

Therefore area of three circular plates = 3\times \pi\times 10^2

=300\pi square cm

Total area of L- shaped drawer which is not covered by these plates = 1200- 300\pi= 300(4-\pi) =257.142857143≈ 257.143 square cm.

<u>Given </u><u>:</u><u>-</u>

  • The slope of the line through points (3,y) and (4,10) is 7 .

<u>To </u><u>Find</u><u> </u><u>:</u><u>-</u>

  • The value of y .

<u>Solution</u><u> </u><u>:</u><u>-</u>

As we know that the slope of the line is difference of ordinate divided by the difference of absicca as ,

\longrightarrow m = y -10 / 3 - 4

\longrightarrow 7 (-1) = y -10

\longrightarrow -7 = y -10

\longrightarrow y = 10 -7

\longrightarrow y = 3

<u>Hence</u><u> the</u><u> required</u><u> answer</u><u> is</u><u> </u><u>3.</u>
