To find the answer we can break the figure into two parts: a rectangle and a semi circle.

The perimeter of the rectangle:

(10+4)×2

=28 ft

The perimeter of the semi circle:

perimeter of a circle: 2×兀×radius

(The radius: 4/2)

We divide the perimeter by two as it is a semi circle,which is half the circumferece perimeter of a circle.

[2(3.14)(4/2)] / 2

=6.28 ft

We can then add up the numbers to find the answer, and remember that 4 cm is overlapped:

28+6.28-4

=30.28ft

Therefore the answer is 30.28ft.

Hope it helps!

The sum of the squares of 3 consecutive positive integers is 116. What are the numbers?
irina [24]
1st number = n
2nd number = n+1
3rd number = n+2

sum of the squares of 3 consecutive numbers is 116

n² + (n+1)² + (n+2)² = 116
n² + (n+1)(n+1) + (n+2)(n+2) = 116
n² + [n(n+1)+1(n+1)] + [n(n+2)+2(n+2)] = 116
n² + n² + n + n + 1 + n² + 2n + 2n + 4 = 116
n² + n² + n² + n + n + 2n + 2n + 1 + 4 = 116
3n² + 6n + 5 = 116  Last option.
