a car dealer buys a luxury car for $65,200 and sells it for 85,650. What is the percent increase in the price of the cara car de

nika2105 [10]

Answer:

The percent increase in the price of the car is 31.36%.

Step-by-step explanation:

Given:

A car dealer buys a luxury car for $65,200 and sells it for $85,650.

Now, to find the percent increase in the price of the car.

Cost price of the luxury car = $65,200.

Sell price of the luxury car = $85,650.

So, the price of the car increased by:

Sell price of the luxury car - Cost price of the luxury car.

$=\$85,650-\$65,200\\\\=\$20,450.$

Thus, the price of car increased by $20,450.

Now,to get the percent increase in the price of the car:

$\frac{20450}{65200} \times 100$

$=0.3136\times 100$

$=31.36\%.$

Therefore, the percent increase in the price of the car is 31.36%.

The volume of this CONE is 175π cubic units.

yulyashka [42]

Answer:

1649.33 units³

Step-by-step explanation:

Let the height and the radius be known as "h" and "r" respectively.

Formulae(s):

Volume of cylinder: πr²h
Volume of cone: πr²h/3

Clearly, we can see that the volume of the cylinder is three times greater than the volume of the cone as,

⇒ πr²h = 3(πr²h/3)
⇒ πr²h = πr²h (True)

Determining the volume of the cylinder;

⇒ Volume of cylinder = Volume of cone × 3
⇒ Volume of cylinder = 175π × 3
⇒ Volume of cylinder = 525π
⇒ Volume of cylinder = 1649.33 units³ (2 d.p)

Therefore, the volume of the cylinder is 1649.33 units³.
