I think that the area is 54 I am not sure I haven’t done math like this in a long time
nine divided by five to the sixth power is 0.000576
Answer:
John is 3 and Annie is 5 because to be half of someone's age while being to years younger it would have to be 2 and 4 - but then a year passed and so the are now 3 and 5.
Step-by-step explanation:
There are 25 identical squares arranged inside the 5 by 5 square matrix. From the drawing it's evident that the length of the side of any one of the smaller squares is just 1. Thus, the perimeter of this one smaller square is P = 4(1), or 4.
The desired perimeter is 4.
Perimeter:
We have two straight, congruent sides from the square that are 24 cm, and two semi-circles (or one whole circle).
24 + 24 + 1/2(24pi) + 1/2(24pi)
48 + 12pi + 12pi
48 + 24pi cm
Area:
We have a semi-circle and a square that is missing a semi-circle. Let's find the area of the square minus the semi-circle, then add the additional semi-circle.
Square = 576
Missing semi-circle = 144pi / 2 = 72pi
Semi-circle = 144pi / 2 = 72pi
576 - 72pi + 72pi
576 cm^2
Hope this helps!
