Answer: \text{one over three }(3.14)(3cm)^2(18cm)

Step-by-step explanation:

The volume of a cone is given by :-

V=\dfrac{1}{3}\pi r^2 h, where r is radius and h is height of the cone.

Given : Diameter of cone : d= 6 centimeters

Then radius of the cone =r=\dfrac{d}{2}=\dfrac{6}{2}=3\ cm

Height of the cone : h=3d=3(6)=18\ cm

Now, the volume of the cone will be :_

V=\dfrac{1}{3}(3.14) (3)^2 (18)

if a one bedroom apartment that rents for $450 in Detroit rents for 250% of that price in manhattan, what is the rent in Manhatt
lesya [120]

Answer:

$1125

Step-by-step explanation:

To find percentage of something, we always take the percentage, convert it to decimal by dividing by 100, and then multiply that decimal with the number given.

Here, we want to find 250% of $450. First, lets convert 250% to decimal:

250/100 = 2.5

So, 250% = 2.5

Now we multiply this with $450 to find rent in Manhattan:

2.5 * 450 = $1125

That's a whooping price of $1125 in Manhattan!!
