Find the central angle of a circle with an area of {eq}74400 {/eq} sq. units and a radius of {eq}75 {/eq}. Let {eq}\pi = 3.14 {/eq}. Area of a Circular Sector: A sector is very similar to a slice of pie or pizza where the vertex is ...
Finding and marking the exact center of a small metal rod or dowel is more difficult than finding the center of a larger circle. I recently wanted to mark the center of a 1" long x 3/8" diameter brass rod, then drill a 1/8" concentric hole the entire length. Yes, just a brass r...
round, two-dimensional figure. The circumference, or distance around the circle, includes a series of points that are all equidistant from the exact center of the circle. The diameter is a line segment that passes from one point on the circle's edge...
A circle with centerGis drawn below. Find the area of the sector indicated in the shaded part below. Give your answer in the exact form in terms ofπ. Step 1:Look at the given figure and identify the radius(r)and the value of central angleθ. ...
Circumference and Diameter of a Circle: In geometry, the circles are the closed 2-dimensional figures of a round periphery such that each point of the periphery always has a fixed distance from a fixed central point. The fixed central point is called the center of the circle, and the fixed...

Verify that the point Q lies on the unit circle and find the exact value of each of the six trigonometric functions if the terminal side of angle x contains Q. Q=(0,1) 相关知识点: 试题来源: 解析 sin x=1, cos x=0, tan x= not \,defined, cot x=0, sec x=not\, defined,...
I recently lost my iPhone. Up until it died it showed it being at the bar I was at the night it went missing. However I and several employees searched everywhere and have not been able to locate it. My question is how precise is the location. The center of the circle is at this ba...
