perimeter = 2πr /2
= 2 × 22/7 /2
= 15.7 + 10 cm
= 25.7 cm
= 2 × 22/7 /2
= 15.7 + 10 cm
= 25.7 cm

D= 10cm
2πr^2
2×22/7×10×10
4400/7
2πr^2
2×22/7×10×10
4400/7
am i not correct
The perimeter of a circle is π × d where d is the diameter so half of that is 1/2 π × d. But If you are going to walk around a semicircleyou need to go half way around the circle and then across a diagonal to get back to where you started so the perimeter is 1/2 π × d + d.
originally copied from Google
there is a difference between multiplying Diameter and Multiplying radius
I can explain u the difference but not here. Mssg me in chat bot
chat box*
otherwise everyone would get disturbed
how can it be wrong!!
this formula is written everywhere
go to mitu's chat box please
