An adapted diagram of this question is attached. You can vary the labelled letters as required.

Definition

A radius is a line drawn from the center of a circle to its circumference.
A segment is a line that connects two points.
A diameter is a chord which passes through the center of the circle.
A chord is any line joining two points on the circles' circumference.

By these definitions:

(a)Segments that are radii of this circle.

We have: |MA|, |MB| and |MC|

(b)Segment that is a diameter of this circle.

|BD|

(c)A chord of this circle that is not a diameter.

If the volume of the rectangular prism is represented by 6x2 – 2x + 8 and the base area is 2x – 4, which expression represents t

Harlamova29_29 [7]

$\bf \textit{volume of a rectangular prism}\\\\ V=Lwh~~ \begin{cases} L=length\\ w=width\\ h=height\\ \cline{1-1} V=6x^2-2x+8\\ \stackrel{base}{Lw}=2x-4 \end{cases}\implies 6x^2-2x+8=(2x-4)h \\\\\\ \cfrac{6x^2-2x+8}{2x-4}=h\implies \cfrac{\begin{matrix} 2 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~(3x^2-x+4)}{\begin{matrix} 2 \\[-0.7em]\cline{1-1}\\[-5pt]\end{matrix}~~(x-2)}=h\implies \cfrac{3x^2-x+4}{x-2}=h$

Surface area of a cylinder

djverab [1.8K]

You can take pi as 22/7 or 3.14

CSA of cylinder = 2*pi*r*h
TSA of cylinder = 2*pi*r^2 + 2*pi*r*h
= 2*pi* ( h+r)
