Answer:
9.42
Step-by-step explanation:
C=2πR
because your diameter is 3, your radius is 1.5, so just plug in your number.
C=2π(1.5)
C=9.42
Figure on top is 8 times 9 (to find volume)
the figure on top has a volume of 72 cm<span>^3
the volume of the lower figure:
3 times 9 times 5 = 135 cm</span><span>^3
72+135=207 cm</span><span>^3
the volume of both figures is 207 cm</span><span>^3</span>
To find the missing values you need to understand that the reciprocal is the fraction that is created when you invert (flip) The fraction.
Using this we actually have the missing values in the other fraction.
Please see the attached picture for the 3 missing values. They are in the boxes.
Answer:
12 mi.
Step-by-step explanation:
a^2+b^2=c^2
c is the hypotenuse (the line across the right angle) and a and b are the other sides.
a=5
c=13
Plug into the equation
5^2+b^2=13^2
b^2=169-25
b^2=144
b=12
