Rounding to hundreds or thousands

1 answer:

4 0

Answer: E.G. 70 rounded to the nearest 100 is 100. It rounds up because it is higher than 49, which would round down

500 rounded to the nearest 1000 would be 1000 because it is over 500.

Anything over five will be rounded up (5,6,7,8,9)

Anything under 5 will be rounded down (1,2,3,4)

Hope this helps!

Answer:

Arc length is $\dfrac{3\pi }{4}\ \text{inches}$

Step-by-step explanation:

We have,

Central angle is 15 degrees and the radius of the circle measures 9 inches.

It is required to find the arc length of the sector.

The relation between arc length and the central angle is given by :

$\dfrac{\text{arc length}}{\text{circumference}}=\dfrac{\theta}{360}$

Circumference, $C=2\pi r=18\pi$

$\theta=15^{\circ}$

$\dfrac{x}{18\pi }=\dfrac{15}{360}\\\\\dfrac{x}{18\pi }=\dfrac{1}{24}\\\\x=\dfrac{18\pi }{24}\\\\x=\dfrac{3\pi }{4}\ \text{inches}$

Hence, the correct option is (b).

Edging is 18.84m. to find the edging you must do the radis times 2, then that answer by pi (3.14). So you do 3x2=6, then 6x3.14=18.84m
