Answer:

$A=600\pi$ $cm^{2}$ ; Approx. 1884.95559215 $cm^2$

Step-by-step explanation:

$A=2\pi rh+2\pi r^2\\A=2\pi 10*20+2\pi 10^2\\A=400\pi +200\pi \\A=600\pi$

Two ropes are attached to a large ballon in a parade. The people holding the ropes are 40 feet apart,and the angle between the t

qaws [65]

Ropes are 9.63 meters ans 8.178 meters.

Step-by-step explanation:

Step 1 :

List all the given things

Distance between people holding ropes = 40 =(40*0.3048) meters = 12.192 meters

Angle between two ropes = 86 degrees

Angle of elevation of one rope = 42 degrees

Step 2 :

Two angles of triangle are already given so third angle can be calculated as -

Third angle = 180 - ( 86 + 42 ) = 52 degrees

Step 3 :

As we know all three angles we will apply sine rule now, which is

$\frac{a}{sine A} = \frac{b}{sine B} = \frac{c}{sine C}$

Step 4 :

By putting values, we have

$\frac{a}{sine 52} = \frac{b}{sine 42} = \frac{12.192}{sine 86}$

Step 5 : Calculating a and b

$a = 12.192 * \frac{sine 52}{sine 86}$ , $b = 12.192 * \frac{sine 42}{sine 86}$

Step 6 :

By putting values of all sine and calculating we get,

a = 9.63 meters and b = 8.178 meters

Ratling [72]

Are you saying that $1050 was the initial amount of money in the savings account? If so then you'd find 84% of 1050, which is 1050*.84. (.84 is the decimal version of 84%)

The perimeter of a rectangular field is 356 yards. If the length of the field is 96 yards, what is its width?

Marina86 [1]

Let x equal the width. Since the length of the base is 96 yards, multiply that times 2 for 192. Then using the parameter formula 2w+2b=P, you get 2x+192=356. Subtract both sides by 192, then divide by 2.
