Question

Find the area of circle of radius 15cm ( pie 3.14)​

Answer 1

Given:-

• Radius = 15cm
• π = 3.14 cm

Area of Circle:-

• Area of Circle =
  `\sf{\pi \: {r}^(2) }`
• Area of Circle = 3.14 × 15²
• Area of Circle = 3.14 × 15 × 15
• Area of Circle = 3.14 × 225
• Area of Circle = 706.5 cm²

Answer:- 706.5 cm² ✅

Answer 2

Answer: A = 706.5 cm^2

Explanation:

Our task is to find the area of the circle; we know that:

• its radius is 15 cm

Applying the formula:

`\sf{A=\pi\,r^2}`

Where:

A = area;

`\pi` = pi (3.14)

r = radius

Plug in 15 for the radius:

`\sf{A=\pi*15^2}`

`\sf{A=225*3.14}`

`\sf{A=706.5\:cm^2}`

`\therefore` Area = 706.5 cm^2
