Travka [436]

Answer:

B

Step-by-step explanation:

We know that:

-measuring a cone
-diameter: 18 units
-height: 8 units

We need to know how to find the volume of this cone. To do this, we need the equation to find the volume of a cone:
V= \pi r^2\frac{h}{3}                   where r=radius and h=height

Upon assessing this equation we also now know that we are missing a radius.

For a circle, the radius is the distance from the midpoint, center, to the border of the circle. The diameter is the distance from the border of one circle to another, passing through the midpoint. Knowing this, we can conclude that the diameter is two times the radius.

Using this information we can figure out the radius for this cone: 9 units.

Now that we have the radius, we can plug in the rest of the numbers with the correct placements.

V= \pi 9^2\frac{8}{3}                    square the 9 by calculating 9 times 9.

V=\pi*81*\frac{8}{3}             combine like terms and keep pi separate.

V=216\pi cubic units
Since this problem is asking for volume, we will used cubic units.

BigorU [14]

Answer:

Step-by-step explanation:

Alice borrowed 16700 from the bank at a simple interest rate of 9% to purchase a used car. It means that the interest is not compounded. Simple interest is usually expressed per annum. The formula for simple is

I = PRT/100

Where

I = interest

P = principal(amount borrowed from the bank)

R = 9% ( rate at which the interest is charged

T = number of years

At the end of the loan,she had paid a total of 24215. This means that the interest + the principal = 24215

Therefore,

The interest = 24215 - 16700 = 7515

Therefore

7517 = (16700 × 9 × t)/100

751700 = 150300t

T = 751700/150300

T = 5 years

Converting 5 years to months,

1 year 12 months

5 months = 12 × 5 = 60 months

HELP ASAP WILL GIVE 100 POINTS.<br> Solve for x. <br><br> 89(54x−36)+2=−34(−40+16x)+90x
PolarNik [594]

Solution:

<u>Simplify the equation and solve.</u>

  • 89(54x − 36) + 2 = −34(−40 + 16x) + 90x
  • => 4806x − 3204 + 2 = 1360 - 544x + 90x
  • => 4806x = 1360 - 454x + 3202
  • => 5260x = 4562
  • => x = 4562/5260 = 2281/2630

The solution to the problem is 2281/2630.
