Answer:

[tex] \bf \huge 78.5 \: c.m.[/tex]

Step-by-step explanation:

Given that :

  • A circle has a radius of 5 centimeters.

to find :

  • What is its area?

formulas used :

  • A = πr²

where,

  • A = area
  • π = 22/7
  • r = radius

explanation :

finding the area of circle

⟼ A = πr²

⟼ A = 22/7 × 5²

⟼ A = 22/7 × 5 × 5

⟼ A = 3•14 × 5 × 5

⟼ A = 3•14 × 25

⟼ A = 78•5

∴ the area of circle is 78•5 centimeters
the area is 78.5 cm because the formula is A=3.14r^2 or area=3.14•5^2
