The area of the circle is determined through the equation,
A = πr²
Plug in the value of area
36 in² = πr² ; r = 3.385 in
The formula for the circumference of the circle is,
C = 2πr
Substitute the value of radius,
C = 2π(3.385 in) = 6.77π in
Thus, the circumference of the circle is 6.77π inches.

Answer:
-26, -25
Step-by-step explanation:
The average of the two is their sum divided by 2: -51/2 = -25.5. The average of consecutive integers is halfway between them.
Hence, one is -26 and one is -25.
Answer:
The surface area of the prism is 
Step-by-step explanation:
we know that
The surface area of the triangular prism is equal to
where
B is the area of the triangular face
P is the perimeter of the triangular face
L is the length of the triangular prism
<em>Find the area of the triangular face B</em>
<em>Find the perimeter of the triangular face P</em>
we have
substitute the values

Step-by-step explanation:
We have the sequence
{
−
16
,
4
,
−
1
,
⋯
}
By looking at the first three terms of the sequence, we can already see a pattern.
Starting at -16, each term has its sign reversed, and is divided by 4.
Hence the sequence can be written as:
{
−
16
,
−
16
(
−
1
4
)
,
−
16
(
−

)
2

⋯
}
So the formula for the

Answer:
43.56
Step-by-step explanation:
22 percent of 198 can be found by converting 22 percent into decimal form which is
22% = 0.22
because a 100% = 1
Then we can multiply 0.22 by 198
0.22*198 = 43.56
So the answer is 43.56
Hope this helps! :)
