How to write the co-ordinates
- If a point is x units away from origin horizontally and y units away from origin vertically then the co-ordinates are written in the form of (x-co-ordinates,y-coordinates)
Now write
- D(2,0)
- C(0,7)
- B(-8,-4)
- A(-6,7)
Answer:
29°
Step-by-step explanation:
cos x = 84/98
x = cos-1(84/98)
x = 28.9
9514 1404 393
Answer:
(a) The figure is a quadrilateral.
Step-by-step explanation:
The four segments are not listed in order around the figure, but they do form a closed loop. The figure is a quadrilateral.
Answer:
3x+6 sq units
Step-by-step explanation:
3(x+2) = 3x + 6
Note that the formula for the circumference of a circle is πd, while the formula for the area of a circle is πr².
π≈3.14
A. C=πd
Simply plug in the numbers into the formula.
Diameter=Radius*2
17*2=34
C=34(π)
B. (π)(5²)
Plug in the numbers into the formula. Remember that half of the diameter is the radius.
C. (π)(4.5)
There are two possible formulas that could be used to calculate the circumference of a circle: πd and 2πr.
The expression above is simply multiplying the circle's radius times pi. Therefore, it is not a method that could be used to find the circumference of a circle.
D. (π)(6.5²)
Remember that the formula for calculating the area of a circle is πr².
Half of the diameter is 6.5 (13.5/2=6.5). 6.5 cm. is the radius. Now just plug the numbers into the formula.
(π)(6.5²)
Therefore, the last answer choice is the correct answer.
