Answer:
Step-by-step explanation:
item 4 Find the perimeter of the window. Round your answer to the nearest tenth. 90 cm
You did not state the diameter or radius of the window
so, i will use 90cm as the diameter of the window
First, I'd calculate the half circumference of the window.
The formula for circumference is 
,
Half of it would just be 
Since our diameter is 90 cm, our radius is 45 cm.
Circumference =
circumference is also the same with perimeter
<h3>so, the answer is 141.37cm</h3><h3>to nearest tenth = 141.4cm</h3>
Answer:
Boiling point of jet fuel = 165 degrees Celsius
Step-by-step explanation:
Given:
Boiling point of jet fuel = 329°F
Find:
Boiling point of jet fuel in degrees Celsius
Computation:
C = [5/9][F – 32]
C = [5/9][329 – 32]
C = 165
Boiling point of jet fuel = 165 degrees Celsius
Answer:
See below
Step-by-step explanation:
a + 133 = 180 because they are supplementary angles. (adjacent angles that form a straight angle)
a = 47 (you substract 133 at each side of the previous equation, leaving that a = 47)
m || n Since "a" measure the same as the angle in the figure that measures 47 both are corresponding angles, therefore m and n are parallels
Answer:
225π
Step-by-step explanation:
substitute V=πr^2h
V=π(5)^2(9)
Simplify.
225π
