One California fan palm tree grew 85 inches in 5 years. A queen palm tree grew 96 inches in 8 years. which tree grew faster? Exp
tester [92]
In 5 years one California Palm tree grew = 85 inches.
Then in 1 year the California palm tree grew = (85/5) inches
                                                                       = 17 inches
Again
A queen palm tree in 8 years grew = 96 inches
In 1 year the queen palm tree grew = (96/8) inches
                                                         = 12 inches.
So the California palm tree is growing at a faster rate than the queen palm tree. This is the easiest way of solving this kind of problems. Hope that i have explained the problem enough for you to understand and attempt such problems in the future without anyone's help.

The central angle of a circle is equal in measure to one radian when the corresponding arc length is equal to which of the follo
irinina [24]
The formula to find the arc length L is
L = r*theta
where r is the radius and theta is the central angle in radians (this formula will not work if theta is in degrees)

If the central angle is 1 radian, then theta = 1 and
L = r*theta
L = r*1
L = r
So the arc length is the same as the radius

Answer: Choice A) The radius of the circle

Find the Area of the figure below, composed of a rectangle and a semicircle.
Mamont248 [21]

Answer:

68.1 units²

Step-by-step explanation:

Start by finding the area of the rectangle...

Area=lw\\Area=6*9\\Area=54

Then, find the area of the semicircle...

Radius=\frac{1}{2}*Diameter=\frac{1}{2}*6=3

Area=\frac{1}{2}\pi r^2\\Area=\frac{1}{2}\pi 3^2\\Area=\frac{1}{2}\pi 9\\Area=\frac{9}{2}\ pi\\Area\approx14.1

Now, add the two to get...

54+14.1=68.1
