Radians = degrees * pi/180 therefore
120 degrees * pi /180 = 2/3 pi
Setup Average Equation:
_____________________
Average=Sum of our 4 numbers + unknown number of x
____________________________________
Total Numbers
15 = 3 + 19 + 8 + 32 + x
______________
5
Cross Multiply
___________
3 + 19 + 8 + 32 + = 15 x 5
x + 62 = 75
Subtract 62 from both sides of the equation to isolate x:
___________________________________________
x + 62 - 62 = 75 - 62
x = 13
Answer:
C. 846 in.^2
Step-by-step explanation:
Look at the net.
There is one rectangle that is (21 + 3 + 21 + 3) inches long. Its length is 48 inches long. Its width is 15 inches.
There there are two small rectangles. Both are 3 inches wide and 21 inches long. The total length is (21 + 21) inches = 42 inches
total area = 48 in. * 15 in. + 42 in. * 3 in.
total area = 720 in.^2 + 126 in. * 3 in.
total area = 846 in.^2
I think the answer is A
I think the answer is A
The surface are of a rectangular prism is:
A=2(xy+xz+yz), where x,y, and z are the dimensions of the prism, in this case:
A=2(4*6+4*8+6*8)
A=2(24+32+48)
A=2(104)
A=208 cm^2
