Answer:
66018.5 sq feet
Step-by-step explanation:
Area = πr²
To find the Radius R we need Diameter which 290 fee so:
R = Diameter / 2
R = 290/2
R = 145 ft
Now put values in Area Formula
Area = 3.14 x (145)^2
A = 66018.5 sq feet
Step-by-step explanation:
k = √(49 - 12√5)
= √(45 + 4 - 2 √180)
= √45 - √4
= 3 √5 - 2.
<em>So, k + 2 = 3 √5 - 2 + 2 = 3 √5.</em>
Answer:
Answers below
Step-by-step explanation:
Radius = 3m
Diameter:
d = 2r
d = 2(3m)
d = 6m
Circumference:
c = 2πr
c = 2π(3m)
c = 6π m
c = 18.85 m
Area:
A = 2πr^2
A = 2π(3m)^2
A = 18π m^2
A = 56.55 m^2

Answer:
The middle two terms cancel out each time, and the final product is x2 plus the product of the positive coefficients of i in the original expression. All imaginary parts either cancel out or get replaced with -1, leaving an expression that doesn’t include imaginary numbers.
