Answer:
The area of the circle is 113.0 ft²
Step-by-step explanation:
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 6ft
π = 3.14
a = π * r²
we replace with the known values
a = π * (6ft)²
a = π * 36ft²
a = 113.04ft²
The area of the circle is 113.04ft²
round to the nearest tenth
a = 113.04ft² = 113.0 ft²

Step by step solution :
Step 1 :
Equation at the end of step 1 :
x + ((((3•19x2) • x6) • x8) • x12)
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
57x28 + x = x • (57x27 + 1)
Trying to factor as a Sum of Cubes :
3.2 Factoring: 57x27 + 1
Theory : A sum of two perfect cubes, a3 + b3 can be factored into :
(a+b) • (a2-ab+b2)
Proof : (a+b) • (a2-ab+b2) =
a3-a2b+ab2+ba2-b2a+b3 =
a3+(a2b-ba2)+(ab2-b2a)+b3=
a3+0+0+b3=
a3+b3
Check : 57 is not a cube !!
Final result :
x • (57x27 + 1)
