I don’t quite understand A B C or D.

Here is my take.

The formula for the volume of a cone is: pi*r^2*h/3. Pi is pi. R is radius. H is height.

So pi * 6*6 * 20/3

The answer is 753.98.

Answer:

240π m³

Step-by-step explanation:

Radius = Diameter/2

Radius = 12/2

Radius = 6 m

Volume of cone = ⅓πr²h

=> ⅓ × π × (6)² × 20

=> ⅓ × π × 36 × 20

=> π × 12 × 20

=> 240π m³

Burka [1]

Answer:

Step-by-step explanation:

1 litre = 1000 ml

water : Sucrose : Saline = 1000 : 269 : 61

This is simplest form. We cannot reduce this as 61 is a prime number and 1000; 269 will not come in 61th table or

We can say 100 ; 269 ; 61 don't have common term

The Schmidts brought a house 10 years ago and took out a mortgage. They are considering selling and want to know how much they s
just olya [345]

Answer: a. They can find the present value of the remaining 20 years worth of payments.

Step-by-step explanation:

The present value of the payments for the servicing of the loan is the amount of the loan that is still owed because the payments include both the interest and the principal repayments.

The Schmidts can therefore find out the amount they still owe by checking the present value of the remaining 20 years worth of payments.

As the payments are usually constant they can be treated as an annuity so using the monthly payment as the annuity, the interest rate as the discount rate and the 20 years ( 240 months) as the period, they should be able to find the present value of the loan.

Two regular polygons with the same number of sides have sides of 6 inches and 8 inches respectively. Find the ratio of their per
DedPeter [7]

Answer:

The ratios of their perimeters is 3/4

Step-by-step explanation:

In this question, we are asked to find the ratio of two perimeter of different regular polygons having the same number of sides but different side lengths.

A regular polygon is a polygon that has its all its sides to be of equal lengths. Now to find the perimeter of this kind of polygon, what we need to do is to multiply the number of sides that we have by the length of one of the sides.

Now, since we know that the number of sides of the polygons are equal, we can say that both polygons each have a total length of n sides each.

For the 6 inch side polygon, the perimeter of the polygon would be 6 * n = 6n inches

For the 8 inch side polygon, the perimeter of the polygon would be 8 * n = 8n inches

The ratio of the two thus becomes;

6n : 8n

This is same as writing 6n/8n

This is equal to 3:4 to the lowest ratio( we first divide by n on both sides, then 2 after wards to arrive at this answer.
