Alla [95]

Answer: 1,296 m iles

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Distance = Speed rate x time

speed rate = 54 miles per hour
time = 24 hours

Replacing with the values given and solving for D (distance)

D = 54 mph x 24 h = 1,296 m

The car traveled 1,296 miles

lys-0071 [83]

Answer:

9,424.8 cm^3

Step-by-step explanation:

V = A of circle x h

= πr^2 x h

=(3.1416)(10)^2 x 30

=(3.1416)(100) x 30

=314.16 x 30

=9429.8

There is a balcony that forms part of a circle around a stage, and they need to put up a safety railing. How long of a railing d

alexandr1967 [171]

A sector is a part of a circle that is formed by two radii, and an arc. So that the length of the safety railing required is 31.4 feet.

A sector is a part of a circle that is formed by two radii, and an arc, thus forming a central angle.

Thus the required length of safety railing can be considered as the arc of the sector.

So that;

length of an arc = (θ / $360^{o}$ ) * 2 $\pi$ r

where θ is the measure of the central angle of the sector, and r is the radius of the sector.

From the given question, θ = 45°, and r = 40 feet.

So that,

length of the safety railing = (45° / $360^{o}$ ) * 2 * 3.14 * 40

= 0.125 * 2* 3.14* 40

length of safety railing = 31.4

Therefore, the length of the safety railing required is 31.4 feet.
