For a cone, if the radius was quadrupled and the slant height was reduced to 1/6 of its original size what would be the formula

Paladinen [302]

Let $r$ be the radius of the cone's base and $\ell$ the slant height.

The surface area of a cone is

$A=\pi r^2+\pi r\ell$

If the radius is quadrupled ( $r\to4r$ ) and the slant height scaled by a factor of $\dfrac16$ , then the new area is

$A=\pi(4r)^2+\pi (4r)\left(\dfrac\ell6\right)$
$A=16\pi r^2+\dfrac23\pi r\ell$

Find the amount and the compound interest on $8000 at 5% per annum for 2 years?

12345 [234]

Answer:

Step-by-step explanation:

Amount = Rs 8820

Compound Interest = Rs 820.

Step-by-step explanation:

We have to find the amount and the compound interest on Rs. 8000 at 5% per annum for 2 years compounded annually.

Let the Principal sum of money = P

Rate of Interest = R

Time Period = T

Amount of money = A

As we know that Amount formula for compounded annually is given by;

Amount =

Now, we are given with P = Rs 8000 , R = 5% p.a. and T = 2 years; we have to find the amount,i.e;

A =

A = Rs 8820

That means Amount = Rs 8820

Also, Compound Interest formula is given by;

Amount = Principal + Compound Interest

Compound Interest = Amount - Principal

= Rs (8820 - 8000)

= Rs 820

Therefore, amount and the compound interest on Rs 8000 at 5% per annum for 2 years compounded annually are Rs 8820 and Rs 820 respectively.

In the diagram, point D divides line segment AB in the ratio of 5:3. If line segment AC is vertical and line segment CD is horiz

BabaBlast [244]

Answer:

C (2, -1)

Step-by-step explanation:

C has the same x coordinate as A = 2

that eliminates A and B.

and the y value of C has to be closer to the y value of B than to the y value of A (due to the 5:3 ratio).

so, without spending unnecessary effort on actual calculation, we can directly derive the correct answer to be C.

but to show in numbers, the "coordinate triangle" of the difference between D and B is a similar triangle to ACD. and so, the ratio of one side pair applies then to all other sides too. including the individual coordinate differences.

so, also the y difference of A to D relates to the y difference between D and B in the same ratio of 5:3 of the overall y difference of A to B.

the y difference A to B is 2 - -6 = 8

the 5/3 split of 8 units is actually 5 and 3.

so, the y coordinate of D is -6 + 5 = -1

and C must have the same y coordinate.

therefore, it is proven that answer C (2, -1) is the right answer.
