Answer:
C.
Step-by-step explanation:
Circumference=PI*diameter
Circumference=3.14*19.5
Circumference=61.23 rounds to 61.2 so the answer is C
2400miles/60hours
40miles/hour
Answer is D
If you want the answer youse a calculator or do 21 divided by 38
ANSWER
36√3 square units.
EXPLANATION
The area of a parallelogram is obtained by multiplying the base by the height.
We use the sine ratio to obtain the height.
![\sin(60 \degree) = \frac{h}{6}](https://tex.z-dn.net/?f=%20%5Csin%2860%20%5Cdegree%29%20%20%3D%20%20%5Cfrac%7Bh%7D%7B6%7D%20)
![h = 6 \sin(60 \degree)](https://tex.z-dn.net/?f=h%20%3D%206%20%5Csin%2860%20%5Cdegree%29%20)
![h = 3 \sqrt{3}](https://tex.z-dn.net/?f=h%20%3D%203%20%5Csqrt%7B3%7D%20)
The area becomes:
![12 \times 3 \sqrt{3} = 36 \sqrt{3} {units}^{2}](https://tex.z-dn.net/?f=12%20%5Ctimes%203%20%5Csqrt%7B3%7D%20%20%3D%2036%20%5Csqrt%7B3%7D%20%7Bunits%7D%5E%7B2%7D%20%20)
Point slope form equation: y - y1 = m(x - x1)
in this case
y - 3 = 1.5(x - 4)
Answer
Point slope form equation:
y - 3 = 1.5(x - 4)
