volume of sphere = V=(4/3)(pi)r^3
so V = (4/3) x 3.14 x 20^3 = 33,493.33 cubic cm

Step-by-step explanation:
first write out equasion
(6/n)-3+9
n=3
6/3=2
2-3=-1
-1+9=8
*quotient means divide, less means subtract, increase means add*
Answer:
-8/3
Step-by-step explanation:
We can find the slope of the line using two points
(1,4) and (4,-4)
m = (y2-y1)/(x2-x1)
= (-4-4)/(4-1)
= -8/3
Answer:
12 feet and 15 feet
Step-by-step explanation:
perimeter = p
perimeter of a rectangle= 2*L +2*w
area of a rectangle = L*w
w= width
L = length
the statement tell us:
area = 180 square feet = area of a rectangle
p = 54 feet
so we have:
180= L*w equation 1
54 = 2*L +2*w equation 2
using equation 2 we have:
2L = 54 -2w
L= (54-2w)/2
L = 27 - w equation 3
using equation 3 in equation 1 we have:
180= (27 - w) * w
180 = 27w -w^2
w^2 -27w +180=0
using quadratic equation : ax^2 + bx +c =0
with a= 1 b= -27 c= 180
we have:
w = 12 feet = width
L = 27 - 12 = 15 feet = length
the dimensions are 12 feet and 15 feet
