A semi-circular rug has a diameter 10 ½cm. Find its area in cm2.(π=22/7)
Answers
Answer : 43.31 cm² ✔️
Solution :
Given that :
A diameter of semi-circle rug = 10 1/2 = 21/2 cm
=> Radius = Diameter/2 = 21/2/2 = 21/4 cm
To find :
Area of semi-circle
As we know that :
Area of Semi-circle = 1/2× πr², where r = radius of semi-circle
Now, Area of semi-circle = 1/2 × 22/7 × 21/4 × 21/4
=> Area of semi-circle = 43.31 cm²
So, the Area of semi-circle will be 43.31 cm²
I hope it will be helpful for you ☺️
