The area given is 380.13
·The equation to find are is pi(r²)=a
·The equation to find the diameter of a circle using the area is a/pi=D
Knowing this we just plug everything in.
·380.13/3.14=D
Now knowing this we solve
380.13/3.14=120.99

Answer:
Step-by-step explanation:
\[d=a_{n}-a_{n-1}=4\]
a1=12
a7=a1+(7-1)d=12+6×4=12+24=36
Answer:
a - b2
Step-by-step explanation:
STEP 1
:
Trying to factor as a Difference of Squares:
1.1 Factoring: a-b2
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : a1 is not a square !!
Ruling : Binomial can not be factored as the difference of two perfect squares
Final result :
a - b2
