Answer: A circle.
Step-by-step explanation:
To solve this exercise is important to remember:
- A sphere is a three-dimensional object whose surface is round.
- A cross section is defined as the intersection of a figure with three dimensions and a plane.
- By definition, all the intersects of a sphere an a plane are circles.
Based on the information shown above, you can conclude that the cross section, which is shown in the figure attached, is a circle.
-41 + (-27 + 2) = 27 - 2 = -25 because negative plus a positive is a negative -41 + -21= -66
The answer would be c I know cause I got it right on the test!
" = inches
' = feet
the scale is 1:30
3" * 30" = 90"
4" * 30" = 120"
the room is 90" by 120"
90" / 12" = 7.5'
120" / 12" = 10'
the room is 7.5' by 10'
7.5' * 10' = 75' ^2
^ = exponential sign (10^2) means 10 to the second power.
The area of the room is 75' ^2
