Question

How many circles of radius 7 cm can be cut from a paper of length 50 cm and width 32 cm
​

Answer 1

Answer:

Step-by-step explanation:

area of the paper(rectangle)=length*breath

here length=50cm and breath=32cm.

=50cm*32cm

=1600cm².................1

area of circle=πr²

here π=22/7 and r=7cm

=22/7*7cm*7cm

=154cm².......................2

divide answer2 from answer1 to get final answer.

⇒1600cm²/154cm²

=  10.3896.......

=10   (approx)

∴10 circle of radius 7 cm can be cut from a paper of length 50cm and width 32cm.

Answer 2

Answer:

10 circle.

Step-by-step explanation:

Given :-

Radius of circle 7cm.

• Rectangular sheet if length 59cm and width 32cm

To find :

Circles that can be formed from that rectangle.

Procedure :

☞ We know area of rectangle = length × breadth.

so , area of this rectangle will be

→ Area of rectangle = 50cm × 32cm

→ Area of rectangle = 1600cm²

☞ We also know that area of circle = πr²

Let's take π as 22/7

$\rightarrow \sf \: area \: of \: circle = \dfrac{22}{7} \times {(7)}^{2}$

$\rightarrow \sf \: area \: of \: circle = {22}{} \times {(7)}^{}$

$\rightarrow \sf \: area \: of \: circle = 154cm$

Dividing the area so as to get the circles which could be cut out.

$\implies \sf \: \dfrac{area \: of \: rectangle}{area \: of \: circle} = \dfrac{1600}{154} = 10.3896circles$

Ignore the decimals , get it as 10.3896 circles , which is approximate to 10circles. So we can make 10 circles of 7cm radius from a sheet of rectangular shape of length 59cm and 32cm.
