Wen was hiking on a 12-mile route. During the first 2 hours, his hiking speed was 3 mph. During the rest of the hike, his speed

Mars2501 [29]

The total time taken to cover 12 miles distance is 5 hours.

<u>Given the Parameters</u> :

Total distance hiked = 12 miles

Recall :

Distance = speed × time

Let :

Total Time taken = t

<u>We could create an equation thus</u> :

Total distance = 3(2) + 2(t - 2)

12 = 6 + 2t - 4

12 = 2 + 2t

12 - 2 = 2t

10 = 2t

t = 10/2

t = 5

Therefore, the total time taken is 5 hours

The volume of a sphere whose diameter is 18 centimeters is how many cubic centiemters

Arturiano [62]

Answer:

3053.63 cm^3

Step-by-step explanation:

Volumme of a sphere = $\frac{4}{3}\pi*r^3.$

We do not have the radius of the sphere, but we have its diameter.

We know that there is a relationship between radius and diameter.

$d = 2r\\r = \frac{d}{2}$

Then the formula of the volume of a sphere according to its diameter is:

$\frac{4}{3}\pi (\frac{d}{2}) ^ 3\\\\\frac{4}{3}\pi(9)^3 = 972\pi = 3053.63 cm^3\\\\$
