Answer:
270 degrees because 1/4 of a circle is 90 degrees
Answer:
x=121
Step-by-step explanation:
√x+1-4=8
1) Combine alike terms:
√x-3=8
2) Add 3 to both sides:
√x=11
3) Cancel the <u>square root</u> by squaring both sides:
x=121
Answer:
Common Difference(d) is

Step-by-step explanation:
Given sequence is :

If a sequence has a constant common difference throughout the sequence, then the sequence is called Arithmetic Progression.
Considering a sequence:


where 'd' is the common difference of the A.P.
Similarly, finding the common difference of the given sequence.



Common Difference(d) is

Answer: one solution

Answer:
=12.56 ft^2
Step-by-step explanation:
First we need to find the radius
r = d/2 = 4/2 =2
Then we can find the area
A = pi r^2
= pi ^ 2^2
= 4pi
= 4*3.14
=12.56 ft^2
