Question

the area of the circular region is 2464cm2.find its radius and diameter ​

Answer 1

Answer:

28

Step-by-step explanation:

area = πr sq.

= 2464

2464*7/22

=. 784

underroot 784

= 28

radius = 28

diameter = 56

Answer 2

Give

• Area of circle is 2462
• radius is ?
• diameter is = R2
• solution

• $\: \: this \: is \: formula \: \\ \:$
• $2462 = \pi \times {r}^{2}$
• $2462 \div \pi = 783.678939784492$
• ${r}^{2} = 783.678939784492$
• $r = 783.678939784492 \div 2 = 391.839469892246 \\ \\ so \: radius \: is \: 391.839469892246 \: and \: diameter \: is \: 783.678939784492$
