Area=pi times radius^2 so
if area=4pi=pi times r^2
4 times pi=r^2 times pi
divide both sdies by pi
4=r^2
square root
2=radius since legnth cannot be negative
radius=1/2 diamters
2 radius=diameter
2(2)=diameter=4
diameter=4
Unless you're given the value of the variables, you can't really solve for anything. The only thing you can do is simplify.
<span>39+5h+4g-2h
The only like terms are 5h and -2h.
39 + 3h + 4g
This would be the simplified version.</span>
2/5 (x-4)=2x answer is x= -1
(1-z) can combine with other coupons
Factor ||5||−||−5||−(−5)|5|-|-5|-(-5) = 25 =5² ( 2 prime factors, 1 distinct)
Divisors = 1,3,25 (3 divesors)
