Answer:

Length of Diameter; 1297 / π

Step-by-step explanation:

If we are to find the exact length of the diameter, it would pose in terms of π, applying the Circumference Formula π * d, where d ⇒ diameter;

Circumference = π * d,

1287 = π * d,

Length of Diameter; 1297 / π

I think it's 1/2, which is 6/12.

5/12 plus 1/12 equals 6/12. 6 is half of 12, so you one half. I hoped this helped.

Answer:

$B_2=4\pi r^2$

see the explanation

Step-by-step explanation:

we know that

The area of the base of a cylinder is given by the formula

$B=\pi r^{2}$

where

r is the radius of the circular base

If the radius is doubled

then

$r=2r$

The new base area is

$B_2=\pi (2r)^{2}$

$B_2=4\pi r^2$

$B_2=4B$

therefore

The new area of the base is 4 times the area of the original base

PLEASE HELP ASAP!!!!!! Quadrilateral PQRS, with vertex P(-5, -3), undergoes a transformation to form quadrilateral P′Q′R′S′, wit

Nana76 [90]

Answer:

The vertex Q' is at (4,5)

Step-by-step explanation:

Given:

Quadrilateral PQRS undergoes a transformation to form a quadrilateral P'Q'R'S' such that the vertex point P(-5,-3) is transformed to P'(5,3).

Vertex point Q(-4,-5)

To find vertex Q'.

Solution:

Form the given transformation occuring the statement in standard form can be given as:

$(x,y)\rightarrow (-x,-y)$

The above transformation signifies the point reflection in the origin.

For the point P, the statement is:

$P(-5,-3)\rightarrow P'(5,3)$

So, for point Q, the transformation would be:

$Q(-4,-5)\rightarrow Q'(-(-4),-(-5))$

Since two negatives multiply to give a positive, so, we have:

$Q(-4,-5)\rightarrow Q'(4,5)$
