A = 2lw + 2lh + 2hw
A = 2(12)(3) + 2(12)(5) + 2(5)(3)
A = 72 + 120 + 30
A = 222 cm squared
Hope this helps!! :)
You can find the perimeter of a circle by using the radius.
circumference = 2

Circumference = 2

circumference = 24 pi
Since you are only trying to find half of the circle you would divide your answer by 2
24pi / 2 = 12 pi
12 pi = 37.68
The answer is B. 37.7
B and c are correct because you use divison and multiplication to get the right answer and the right answer is 99cm
Yes. The triangles are both right triangles, which means they both have a single right angle.
