What is the area of a sector with a radius of 8 and an arc angle of 80 degrees?
Area = r2*A where A is the angle measure in radians. = 8*8*80*pi/180 = 89.361 square units.
How many line segments are there in an octagon?
Eight.
How many corners a brick has?
A brick has 8 corners.
How Many Squares In A 8-by-8 Square?
There are 64 squares as on a chess board. This is assuming that 8 by 8 in the question means 8 rows and 8 columns.
How many side does a octagon have?
It has 8 sides.
How many radians is one eighth of a circle?
Since an entire circle is 2π radians, 1/8 would be π/4
Which angle measure is closest to 8 radians?
The list of choices is difficult to read from here, but 8 radians = 458.366 degrees. (rounded)
How many weeks correspond to 56 days?
There are 56/7 = 8 weeks.
What is the area of a sector with a radius of 8 and an arc angle of 80 degrees?
Area = r2*A where A is the angle measure in radians. = 8*8*80*pi/180 = 89.361 square units.
If a circle needs 8 360 degree rotations to roll 8 meters it's radius is how many meters long?
Circumference is 1 meter so radius = 0.5/pi meters = 0.160 meters/160 millimeters to the nearest thousandth
How many different rectangles can you form using 24 centimeter squares?
It depends on whether rotations are considered the same or different. 1 x 24, 2 x 12, 3 x 8, 4 x 6 are the distinct rectangles if rotations are disallowed. Each of them can be rotated through 90 degrees to give four more if rotated versions are considered different.
How many ways are there to put 8 beads of different colors on the vertices of a cube if rotations of the cube but not reflections are considered the same?
The answer is 1680. When the cube is rotated, there are 8 points a single vertex could end up on, and 3 ways for each vertex to be rotated onto itself. Therefore, it is 8!/(8x3)=40320/24=1680
What is the difference between Saturn Vin 7 and Vin 8?
The VIN codes correspond to the engine in the vehicle. 7 is the code for the DOHC 1.9, while 8 is the code for the SOHC...
Approximately how many meters will a point on the rim of a wheel travel if the wheel makes 50 rotations and its radius is 1 meter?
Circumference of wheel = 2*pi*1 = 2*pi 50/2*pi = 7.957747155 nearly 8 meters
Solve 5 over 8 equals Tan x?
5/8 = tan(x) x = tan-1(5/8) = tan-1(0.625) = 0.558599 + k*pi radians or 32.00538 + k*180 degrees where k is an integer
How long will it take a pulley rotating at 8 radians per second to make 50 complete revolutions?
(1 sec/8 rad) * (2 pi rad/1 rev) * 50 rev = 12.5 * pi seconds about 39.27 seconds
How do you turn an algebraic expression into a phrase?
By recognizing key words that correspond to key parts of the equation. For example, "is" is = "added to " is + "taken away from" is - etc. the equation 5 + 3 = 8 can be written as 5 added to 3 is 8.
