Please help me with this

Volume (V) = 3888π cubic inches

Step-by-step explanation:

The volume of the drawn hemisphere is expressed as:

V = 2/3 π r ^3

Parameters given:

r = 18 inches

r = r ^ 3

= 18^3

= 18 * 18 * 18

r = 5832 inches

Therefore:

Volume (V) = 2/3 * π * 5832

V = 2/3 * 5832 π

V = 2 * 1944π

V = 3888 π cubic inches

Maths is fun!

1) c 2143.6 cm

2) c 113.0 m

3) a 33.5 ft

4)   d 2 cm

5) c 20 mm

6) 180 in

7) d 120 ft

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
