Answer:
a) 
b) 
Step-by-step explanation:
Polar coordinates are represented as: 
, where 'r' is the length (or magnitude) of the line, and '
' is the angle measured from the positive x-axis.
in our case:
to covert the polar to cartesian:
we can plug in our values:
the Cartesian coordinates are:
(b) to convert (x,y) = (6.06,-3.5)
we'll use the pythagoras theorem to find 'r'
the angle can be found by:
to convert radians to degrees:
writing in polar coordinates:
So the base is 72 area squared. You multiply 72 by the height, which is 9, giving you 648 area cubed.
Hope this helped!
Answer:
line mo
Step-by-step explanation:
Because the triangle are congrument
RST and MNO are the triangle
RT is a line in the RST triqangle
it is equal to the MO line in MNO
Answer:
280 Cubic inches
Step-by-step explanation:
When finding the volume, the equation is V=l*w*h
Therefore, the equation should be:
10.1*3.9*6.8
This is equal to exactly 267.852
However, the answer is 280 cubic in. because it's a larger number and it's about 13 from the actual answer. On the other hand, 250 cubic in. is about 17 from the actual number.
