Step-by-step explanation:
area of a circle= πr²
= 3.14 x 6²
=3.14 x 36
= 113.04 cm²
Answer:
x=2
Step-by-step explanation:
2x+4=4x
-2x -2x
4=2x/2x
4/2=x
x=2
Answer:
see explanation
Step-by-step explanation:
The area (A) of a square is calculated as
A = s² ( s is the measure of a side of the square )
Here s = x + 2 and A = 7, thus
(x + 2)² = 7 ← expand left side using FOIL
x² + 4x + 4 = 7 ( subtract 4 from both sides )
x² + 4x = 3 ← as required
Original height = original width = x mm
1. She made an enlarged copy...
height = 2x
width = 2x
2. She cut off a rectangle...
height = 2x
width =

3.She doubled the width...
height = 2x
width =

height * width = area

Original height was
162 mm
