Answer:
The radius of the can is 7.28 cm .
Step-by-step explanation:
By our general knowledge, a "can" is a cylinder. It is given that the volume of can is 2500 cm³ and the height is 15 cm tall so we have to use the formula of volume of cylinder to find the radius :
Let r be radius, v be volume and h be height,
Let v = 2500 cm³,
Let h = 15 cm,
Step-by-step explanation:
7x - 3 = 6x + 17
7x - 6x = 17 + 3
x = 20
Solution → x = 20°
Answer:
3
Step-by-step explanation:
The horse traveled 439.6 feet after walking around the track 5 times
<u><em>Solution:</em></u>
Given that, horse walks around a circular track while its trainer stands in the center
The trainer is 14 feet from the horse at all times
Therefore, radius of circular track = 14 feet
The circumference of circle is the distance traveled by horse for 1 lap
<em><u>The circumference of circle is given as:</u></em>
Where, "r" is the radius and is a constant equal to 3.14
Thus the distance traveled by horse for one time in circular track is 87.92 feet
<em><u>About how far had the horse traveled after walking around the track 5 times? </u></em>
Multiply the circumference by 5
Thus the horse traveled 439.6 feet after walking around the track 5 times
Since the rate is constant, the growth of the height of the helicopter follows a linear pattern. The helicopter has an initial quota of 40ft, so that would be the constant term. The linear terms's coefficient is the rate of growth, so 21 ft/s. So, if is the number of seconds passed from when the observation started, we have
Which means that, if , the height is
