You are given the surface area of the cube which is 96cm2. You are asked to find the length of one side and its volume. Note that the surface area of the cube is equal to 6 times the square root of s (the side of the cube) and the volume is the cube root of s. So,

SA = 6*s^2
96cm2 = 6*s^2
s^2 = 16cm
<u>s = 4cm, this is the length of one side.</u>

V = s^3
V = (4)^3
<u>V = 64cm3, this is the volume of the cube.</u>

12, 96/8 equals 12, so therefore it is 12 cm cubed

Solve the inequality -2x is less than or equal to 3x + 1 is less than or equal to 10

KatRina [158]

-2x < = 3x + 1 < = 10

split them
-2x < = 3x + 1 3x + 1 < = 10
-2x - 3x < = 1 3x < = 10 - 1
-5x < = 1 3x < = 9
x > = -1/5 x < = 3

solution is : -1/5 < = x < = 3 <==

A bicycle training wheel has a radius of 3 inches. The bicycle wheel has a radius of 10 inches. Approximately how much smaller,

zhuklara [117]

Answer:

$285.74\text{ inch}^2$

Step-by-step explanation:

GIVEN: A bicycle training wheel has a radius of $3\text{ inch}$ . The bicycle wheel has a radius of $10\text{ inch}$ .

TO FIND: Approximately how much smaller, in square inches, is the area of the training wheel than the area of the regular wheel.

SOLUTION:

radius of bicycle wheel $=10\text{ inch}$

area of bicycle wheel $=\pi r^2$

putting value,

area of bicycle wheel $=3.14\times10^2$

$=314\text{ inch}^2$

radius of bicycle training wheel $=3\text{ inch}$

area of bicycle training wheel $=\pi r^2$

putting value,

area of bicycle wheel $=3.14\times3^2$

$=28.26\text{ inch}^2$

difference in area of bicycle wheel and bicycle training wheel

$=\text{area of bicycle wheel}-\text{area of bicycle training wheel}$

$=314-28.26$

$=285.74\text{ inch}^2$

hence the training wheel is $285.74\text{ inch}^2$ smaller than regular wheel
