Question

A circular disc has radius 10cm . Find the area of disc in m2 use n 3.14

Answer 1

Answer: 0.0314 m^2

Step-by-step explanation:

Area of a circle is pi*r2

r=10 cm

pi is given as 3.14

Area = 3.14 * 10 * 10

= 3.14 * 100

= 314 cm2

=0.0314 m2 (because m2 = 100 * 100 cm2 = 10000 cm2, 314 cm2 = 314/10000 m2 = 0.0314 m2)

Answer 2

Answer:

314cm2

Step-by-step explanation:

• area is circle=pi r2
• 3.14×10×10
• = 31.40×10 =314.00cm2
• Therefore,area of circle = 314cm2
