Answer:
The volume of the sphere is 1436 in³
The equation is
V = ⁴⁄₃ * 3.14 * (7ft)³
Step-by-step explanation:
radius = half of diameter
d = 14ft
r = 14ft / 2 = 7ft
To calculate the volume of a sphere we have to use the following formula:
V = volume
r = radius = 7ft
π = 3.14
V = ⁴⁄₃πr³
we replace with the known values
V = ⁴⁄₃ * 3.14 * (7ft)³
V = 4.187 * 343 in³
V = 1436 in³
The volume of the sphere is 1436 in³

Answer:
325
Step-by-step explanation:
Writing out the equation always makes it easier to solve:
( 21 / 7 ) + 7 + 7( 7 - 2 ) x 9
First, following the rules of P.E.M.D.A.S.
(parenthesis, exponents, multiplication, division, addition, subtraction.)
You would need to solve for the values within each parenthesis... so
(21 / 7). 21 divided by 7 is equal to 3. And in (7 - 2). 7 minus 2 is equal to 5.
The equation is now:
( 3 ) + 7 + 7( 5 ) x 9
Next you must solve for multiplication, so:
7( 5 ), 7 times 5 is 35. the equation is now:
( 3 ) + 7 + ( 35 ) x 9
Then, 35 x 9 is equal to 315. The equation is now:
( 3 ) + 7 + 315.
If you add everything together, you get the answer of:
325!!!
