radius ( r) = 1 cm
The volume (V) of a sphere is calculated using the formula
V =
πr³
here V is given as V =
π
Equating gives
V =
πr³ =
π
dividing both sides by
π, gives
r³ = 1 ( take the cube root of both sides )
r = ∛1 = 1
Step-by-step explanation:
- you just substitute (-2) into the x values of the above function

Answer:
V = 10,240mm^3
Step-by-step explanation:
The volume of pyramid is given by the following formula:
(1)
b: base of the pyramid = (32mm)^2
h: height
Thus, it is necessary to find the value of h, by using the Pitagoras's theorem, one half of the base and the slant height (which forms a rectangle triangle with h):

by replacing in (1) you obtain:

hence, the volume is 10240mm^3
Answer:
FIRST OPTION.
THIRD OPTION.
FIFTH OPTION.
Step-by-step explanation:
Let be "x" the number of of female volunteers and "y" the number of male volunteers.
You need to remember the meaning of the inequalities symbols:
: Less than.
: Greater than.
: Less than or equal to.
: Greater than or equal to.
In this case you know that the illusionist needs up to 10 volunteers, which indicates that the total number of volunteers can be less than or equal to 10 people. The inequality that represents this is:

According to the exercise, the illusionist needs no fewer than 4 female volunteers. This means that number of female volunteer must be greater than or equal to 4:

Since the number of female volunteers could be 10 (Because can be greater than 4), it could not be male volunteers. This means that:
