Answer:

FALSE
TRUE
TRUE

Step-by-step explanation:

1.

Non-standard units can be used to measure volume
Examples : m³, in³, cm³, mm³, L

2.

The volume of a rectangular prism can be found by multiplying the length, width, and height
V = lwh

3.

If there are smaller units, then naturally more of the units will be used
If there are larger units, then less of the units will be used

The formula for the volume of a right circular cone, V, is given below, where r represents the radius of the base of the cone an

Mrrafil [7]

Answer:

$r=\sqrt{\frac{3V}{(\pi h)}}$

Step-by-step explanation:

we know that

The volume of a right circular cone is equal to

$V=\frac{1}{3}\pi r^{2}h$

where

r is the radius of the base of the cone

h is the height

Solve for r-----> That means, isolate the variable r

step 1

Multiply by 3 both sides

$3V=\pi r^{2}h$

step 2

Divide by $(\pi h)$ both sides

$\frac{3V}{(\pi h)}=r^{2}$

step 3

take square root boot sides

$r=\sqrt{\frac{3V}{(\pi h)}}$

The length of a rectangle is 17 inches more than twice its width, and its area is 69 square inches. What is the width?

Fantom [35]

Answer:

Width = 34.5 inch OR 26 inch

Step-by-step explanation:

Let the length of the rectangle be 'L' and

Width of the rectangle be 'W'

Length = 2*Width+17

L=2*W+17

Area = 69 square inches

Area of the rectangle=

$Length * Width\\\\ 69 = (2W+17)*W \\\\ 2W^2+17W=69$

Dividing by '2' both the sides:

$W^2+8.5W=34.5\\\\W(W+8.5)=34.5\\\\W=34.5inch\\OR\\W+8.5=34.5\\W=34.5-8.5\\W=26 inch$

W=34.5 inch OR W=26 inch
