A measuring wheel is used to calculate the length of a path. The diameter of the wheel is 8 inches. If the wheel rotates 15 time
Oksi-84 [34.3K]
To fint the length first one must find circumference to do that we use the formula D*Pi (diameter times Pi. Diameter = 8 Pi is the constant of 3.1415
so. 8*3.1415 = appox 25.1327. cow that we have  circumference we should multiply by the amount of times the wheel rotates (15)
so. 15*251327 = appox 376.9911in now convert to feet. 12 in = 1 foot so divide by 12
so 376.9911 / 12 = about 31.4

Find the volume of this figure. round your answer to the nearest hundredth. if necessary<br><br>#8
ivann1987 [24]

Answer:

30 miles²

Step-by-step explanation:

To solve the area of the prism we have to multiply the area of the base * the height of the prism. The base of the prism is a right triangle.

<em>(b*h)÷2 = Area of a triangle</em>

<em />

<em>Base = 4</em>

<em>Height = 3</em>

<em>Now:</em>

<em>(4*3)/2 = 6 miles²</em>

<em />

<em>Now we have to multiply 6 miles² by 5 as our height.</em>

<em />

<em>We get 30 miles² as the volume of the figure.</em>
