Question

Find the area of the circle use 3.14 for it d = 10 cm a = ? cm^2 NO TROLLS TY

Answer 1

Answer:

78.5 cm²

Step-by-step explanation:

GIVEN :-

• Diameter of the circle (d) = 10 cm
• π = 3.14

TO FIND :-

• Area of the circle (a)

FORMULAES TO BE USED IN THIS QUESTION :-

• $Radius = \frac{Diameter}{2}$
• $Area = \pi \times (Radius)^2$

SOLUTION :-

$Radius\: (r) = \frac{Diameter}{2} = \frac{10}{2} = 5 cm$

$=> Area = \pi r^2$

               $= 3.14 \times (5)^2$

               $= 3.14 \times 25$

               $= 78.5 \: cm^2$
