Answer:
21π m, or ≈ 65.94 m
Step-by-step explanation:
Remember that π is the ratio between a circle's circumference and its diameter, or, in equation form:
where c is the circumference and d is the diameter. If we want to find the <em>circumference</em>, we can just multiply that equation by d on both sides to get
Here, our d = 21 m, so our circumference would be
m, or approximately 21(3.14) = 65.94 m
It would be 2 bc u couldn’t round 0 because it’s less then 5
Answer:
x² + 10x + 25
Explanation:
Before we begin, remember the following:
(a + b)(a + b) = (a + b)² = a² + 2ab + b²
Now, for the given we have:
(x + 5)(x + 5)
We can note that the two brackets are identical.
Therefore, we can apply the above rule as follows:
(x + 5)(x + 5) = (x + 5)²
= (x)² + 2(x)(5) + (5)²
= x² + 10x + 25
Hope this helps :)
6 - 5/2
which in turn results into 7 halfs
(7/2)
