A Piece Of Wire In The Form Of Reactangle 40 Cm Long And 26 Cm Wide Is Again Bent Tp Form A Circle Find The Radius Of The Circle.

a piece of wire in the form of reactangle 40 cm long and 26 cm wide is again bent tp form a circle find the radius of the circle.

  Find the perimeter of the rectangle first
P = 2 (l + w)
P = 2(40+26)
P = 2 (66)
P = 132 cm
P of rectangle is equal to the circumference of the circle
C = 2πr
132 = 2πr
r = 66/π
r = 21.02 cm

A New Square Is Formed By Joining The Midpoints Of The Consecutive Sides Of A Square 8 Inches On A Side. If The Process Is Continued Until There Are A

A new square is formed by joining the midpoints of the consecutive sides of a square 8 inches on a side. If the process is continued until there are already six squares, find the sum of the areas of all squares in square inches. a. 96 b. 112 c. 124 d. 126   Area of the Square: The sum of the areas of all six squares formed by joining the midpoints of the consecutive sides of a square 8 inches on a side in square inches is 126. Given: square 1 – 8 inches per side Solution: Solve for the area of the first square using the formula A = s² such that,  A = (8 inches)² = 64 inches².  Therefore, area of the first square is 64 inches². Given that the next square is formed by connecting the midpoints of the first square then we can get the area of the second square by dividing the area of the first square by 2 which is 64/2 = 32. Thus, the area of the second square is 32 inches². Get the area of the third square by dividing the area of the second square by 2 which is 32/...
