Question

5. Find the area of the circles with radius:
b) 56 mm
​

Answer 1

Answer:

A=3.14(56)²

A=3.14×56×56

A=9847.04mm

Answer 2

Given :

⬤ Radius of Circle is 56 mm .

To Find :

⬤ Area of Circle .

Formula Used :

$\bf[\:{Area \: of \: Circle = \pi{r}^{2}}\:]$

Solution :

According to the Formula :-

πr²

22/7 × 56 × 56

22 × 56 × 8

9856

Therefore , Area of Circle is 9856 mm² .

Related Formulas :

• Circumference of Circle = 2πr
• Area of Circle = πr²
• Curved Surface Area of Cone = πrl
• Total Surface Area of Cone = πr (r + l)
• Volume of Cone = ⅓πr²h
• Curved surface area of Cylinder = 2πrh
• TotalSurface Area of Cylinder = 2πr (r + h)
• Volume of Cylinder = πr²h
