Hey there!
Given that this flower bed is circular, it can be assumed that it's a cylinder. In this problem, we need to use the equation for the volume of a cylinder:
V = π r² h
Since we just need to find the area that the mulch will take up, we'll use that given measurement of 4 inches in place of the actual height of the flower garden. Since we need the radius, all we have to do is divide the 12 inch diameter measurement in half to get a radius of 6 inches. Usually for these problems, they'll tell you to use 3.14 for pi instead of the full pi number, so we'll just use that to make things easier.
V = π (6)² (4)
V = π (36)(4)
V = π (144)
V = 452.16
The volume of the mulch needed will be 452.16 in³.
Hope this helped you out! :-)
Cotxcos2x = 2cotx
cos2x = 2cotx/cotx
cos2x = 2
cos2x = 2cos²x - 1
2cos²x - 1 = 2
2cos²x = 2+1
2cos²x = 3
cos²x = 3/2
√cos²x = plus minus √(3/2)
cosx = plus minus √(3/2)
The answer would be 40.
to answer this, u can use the is over of equals to % over hundred.
is %
__ = ___
of 100
the is would be 24 and the percent would be 60.
so,
24 60
__ = ___
x 100
to answer this u would cross multiply.
24x100=2400
60x X=60x
then, divide
6\0x 2400
__\___ = _____
6\0 60
2400 divided by 60 is 40.
40 is the answer.
Speed=distance/time
we need to findn her distance in miles and times in hous
440 yards times 4 laps=1760 yards
1760 yards=1 mile
distance=1 miles
time
10 minutes
60 minutes per hour
1/6 hour
1 miler per (1/6) hour
multiply by 6
6 miles per 1hour
6 miles pe hour
Answer: w= -4
Step-by-step explanation:
7w-180=52w
Subtract 7w on both sides.
-180=45w
Divide both sides by 45.
-4=w
