Answer:
If the area of a circular rose garden is 44 square meters, then we can write:
44 = πr^2
And since π is equal to 22/7, we have:
44 = 22/7(r^2)
Multiply both sides by 7/22 to cancel the 22/7:
14 = r^2
And finally, we see that the radius of the garden is:

Answer:
(9m-1)(9m+1)
Step-by-step explanation:
This is a difference of squares
(9m)^2-1^2
Use a^2-b^2=(a-b)(a+b)
So the answer is (9m-1)(9m+1)
Yes! It can simplified to 2/5 or in decimal form it would be 0.4 . Hope this helps!
Answer:
w < 1.5
Step-by-step explanation:
We solve these almost identical to solving equations. By going backwards in the process.
14 - 12.5 = 1.5
w < 1.5
Hope this helps!
