Answer 1

Answer:

Circumference=2 pie.r and area=pie r²

for circle apply and find radious then put

Answer 2

Answer:

Area of circle is $200.96\ cm^{2}$ .

Step-by-step explanation:

To find : area of circle .

Given : circumference of circle is 50.24 cm .

Solution :

• As per given that we know that circumference of circle is 50.24 cm . We are asked to find area of circle.
• We use following formula to find circumference of circle, using this formula we find radius of circle by substituting the given values.
• Circumference of circle $= 2\pi r$

        $50.24 =2\times3.14\times r\\\\50.24 = 6.28\times r\\\\r = \frac{50.24}{6.28}\\\\r = \frac{5024}{628} \\\\r = 8\ cm$

• Now , as we know radius of circle is $8$ cm we can find area of circle using following formula .
• Area of circle = $\pi r^{2}$

                               $= 3.14\times (8)^{2} \\\\ = 3.14 \times64 \\\\ = 200.96\ cm ^{2}$
