Well,we know that the circumference of a formula is 2*pi*r According to the question,the circumference is 272.2 inches pi=3.14 We equate the two equations we have so far. 2*pi*r=272.2 2*3.14*r=2.72 Can you find the value of r from here @rainbowswirl ?
How do I find the value of r? I cant remember :( @bournville
@mathstudent55
Well,you dun know algebra?Shall I do it for ya?
Could you explain, please? @Vijeya3
Okay,let us take it step by step.This is how we do it We have the equation 2*3.14*r=272.2 Now we need to get rid of the values 3.14 and 2 on the left hand side Does this make sense to you?
Yes @Vijeya3
Good To do this,we divide both the sides of the equation by 2 first. Like this |dw:1458913549923:dw| Can you tell what the resulting equation will now look like?
