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 sides are in a polygon with 8 sides?
There are 8 sides in the polygon with 8 sides (an octagon).
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.
How many radians are there between the hands of a clock at eight o' clock?
At eight o'clock, the hour hand is on the 8, and the minute hand is on the 12. The clock is divided into 12 hours, with each hour representing ( \frac{\pi}{6} ) radians. The angle between the 8 and the 12 is ( 4 \times \frac{\pi}{6} = \frac{2\pi}{3} ) radians. Therefore, there are ( \frac{2\pi}{3} ) radians between the hands of the clock at eight o'clock.
What is the arc length of the arc subtended in a circle with radius 6 and an angle of 7 8?
To calculate the arc length ( L ) of a circle, you can use the formula ( L = r \theta ), where ( r ) is the radius and ( \theta ) is the angle in radians. First, convert the angle ( 7/8 ) from degrees to radians. Since ( 7/8 ) of a full circle (360 degrees) is ( \frac{7}{8} \times \frac{\pi}{180} ) radians, you get approximately ( 0.0154 ) radians. Then, substitute the values into the formula: ( L = 6 \times \frac{7}{8} = \frac{42}{8} = 5.25 ) units.
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 element in period 4 and group 8?
In the periodic table, period 4 and group 8 correspond to the element krypton (Kr). There is only one element in period 4, group 8. Krypton is a noble gas and is known for its inertness and use in various lighting applications.
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.
Does the product of 5 reflections and 8 rotations of the x-y plane produce a rotation or a reflection?
The product of an odd number of reflections results in a reflection, while the product of an even number of reflections results in a rotation. In this case, 5 reflections produce a reflection. Adding 8 rotations (which do not affect the outcome of the reflections) does not change that result. Therefore, the overall transformation is a reflection.
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
