Question

Someone help me with this ​

Answer 1

Let's see

• Area=110
• πr²=110
• 22/7r²=110
• r²≈110(7)/22
• r²=770/22
• r=√770/22
• r=5.9mm

Answer 2

radius = √35 mm or 5.916 mm

Step-by-step explanation:

• 
  `\sf area \ of \ circle = \pi r^2`

Here:

• area of circle: 110 mm²

• π taken as 22/7

Solve for radius:

`\rightarrow \sf \pi r^2 = 110`

`\rightarrow \sf (22)/(7) r^2 = 110`

`\rightarrow \sf r^2 = (110(7))/(22) =35`

`\rightarrow \sf r = √(35)`
