Answer:
Part A A. 400 sq ft.
Part B A. 509 sq ft
Step-by-step explanation:
Part A
Area of square = side squared
Since all the sides of the square are congruent and the perimeter is 80, then the length of each side is 80/4 = 20
A = 20^2 = 400 sq ft
Part B
C = πd
80 =
80/π = d
r = d/2 = 80/2π = 40/π
A = πr^2 = π(40/π)^2
= 1600π/π^2 = 1600/π = 1600/3.14 = 509 sq ft
Answer: It is impossible to sqare a real number and get a number.
Step-by-step explanation:
Answer:
Assuming the number is 9.094 the answer is 9.094 If it is whole number it is 9000
Step-by-step explanation:
The tens place is .0
The Hundreds place is .09
The thousands place is .094
if you are talking about whole numbers: it's 9000
When rounding, 5 and above it is rounded up, and 4 and below is rounded down.
So for this problem you only need to look one place to the right.
9<u>0</u>94 Because that number is 0 that means you round down.
