If the radius of a semi circle was 135cm squared what would the circumference be? Please round to the nearest centimetre to make it easier for me. I will give brainliest.

Respuesta :

I’m assuming that u meant 135cm and NOT 135cm squared because radius is length


First find the circumference of the entire circle
= 2 x pi x radius
= 2 x pi x 135
= 848 cm

Next divide it by two because it is semi circle

=848 / 2
= 424cm

This length is only for the curved part of the semi circle. If u want the full length around it add it to the diameter which is twice the radius
