this shape is composed of 4 squares and 4 quarter circles select all the expressions that represent it's perimeter. the squares and quarter circles are 7.
So is it A. 42 + 14 pi
B. 7+7+7+7+7+7+14 pi
C. 91+ 14 pi
D. 7+7+7+7+7+7+7+7+7+7
E. 147+ 49 pi
The shape is composed of 4 squares and 4 quarter circles.
The perimeter of each square is 7, so the total perimeter of the squares is 4 * 7 = 28.
The perimeter of each quarter circle is the circumference of a circle with radius 7 divided by 4. The formula for the circumference of a circle is 2 * pi * radius, so the perimeter of each quarter circle is 2 * 3.14 * 7 / 4 = 10.99 (approximately).
The total perimeter of the quarter circles is 4 * 10.99 = 43.96 (approximately).
Therefore, the total perimeter of the shape is 28 + 43.96 = 71.96 (approximately).
None of the given expressions match this value. So none of the expressions represent the correct perimeter of the shape.
