Answer:
We know length of one quarter of a circle = 2πr/4 = πr/2
So here we can make the equation for to find thr value of radius r
length of one quarter given = 25 cm
so πr/2 = 25 cm
=> πr = 50 cm
=> r = 50/π cm
So the entire circumference of circle =
2πr
= 2 π 50/π cm
= 100π/π cm (ans)
Here we dont substitute the value of π due to represent the answer in terms of pi.
Hope it helps you
Hello luv! So here is how I will evaluate this expression
-4x+7, x=-1 so you are using substitution
-4(-1)+7
=11
:)
If the temperature drops 35 degrees everyday for 7 days, you would have to add -35 + -35 + -35 +-35 + -35 + -35 + -35, since each day it drops the temperature would be -35, now the answer would be -245.
Hopefully this helped. :)
