Answer: 
Explanation:
Multiplying by 1/2 is the same as dividing by 2.
For example, if you have 10 slices of cake and 2 friends, then each friend gets 10/2 = 5 slices. We could also say 
The fraction 1/2 converts to the decimal form 0.5, which means 
the volume of the cylinder is 572.27 cm³
Explanation:
Given:
radius of the cylinder = 4.5cm
height = 9cm
To get the volume of the cylinder, we will use the formula:
To the nearest hundredth, the volume of the cylinder is 572.27 cm³
Answer:
51 gal
Step-by-step explanation:
Find the area of the wall you need to paint:
12 m * 80 m = 960 m^2
Use conversion rate to convert square meters to square feet (first, make the conversion rate into square meters instead of regular meters):
1 ft / 0.3048 m -> 1^2 ft / 0.3048^2 m^2
960 m^2 * (1 ft^2 / 0.3048^2 m^2)
Square meters cancel out, we are left with square feet:
960 * (1 ft^2 / 0.3048^2) = 10333.354 ft^2
Now, find how many gallons of paint by dividing by 200 square feet:
10333.354 ft^2 / 200 =~ 51.66 gal
Round up to the nearest whole number:
51.66 =~ 51 gal
Answer:
b=42
c=180
Step-by-step explanation:
For a 45 45 90 triangle if the legs are x length then the hyptonuse is x√2
a.
7=x
so hyptonuse=7√2 in
b.
sin(45°)=(√2)/2
c.
not sure what you need SAS for
but, area=1/2 times base times height
base=height=7
area=1/2 times 7 times 7=24.5 square inches
d. not sure, same as above?
