The equation for the area of a circle is A = pi times r^2
The radius is half the diameter, making it 5.
A = pi times 5^2
Simplify to: A = pi times 25
A = 78.5
a. Surface area = 172 cm²
Volume = 112 cm²
b. The surface area would be needed.
c. The volume would be needed.
<h3>How to Find the Surface Area and Volume of a Box?</h3>
Surface area = 2(wl+hl+hw).
Volume = (length)(width)(height)
a. l = 7 cm
w = 2 cm
h = 8 cm
Surface area =2(wl+hl+hw) = 2·(2·7+8·7+8·2) = 172 cm²
Volume = (7)(2)(8) = 112 cm²
b. The surface area would be needed.
c. The volume would be needed to find the amount of juice the box will hold.

It is 42,44, and 46. If you add them all together you get 132 :)
So it's really easy to do this
4 times 2 is 12 and then time 10 degree
=12 times 10 degree
=120 degree
As long any understand that you don't have to change or do anything with the degree and just multiply the numbers .
I hope it helped u
Answer:
+ 2 is a value for "C"
if the general form is ax^2 + bx +c and you want the A to be a positive integer...
then the c value would be -8
3x^2 - 8 = 0
