It is generally useful to use the formula. The procedure is to substitute the given values for the variables in the formula, then do the arithmetic.
... A = (1/2)r²·θ . . . . r is the radius, θ is the central angle in radians
Put the numbers in ...
... A = (1/2)(4 in)²·(π/3)
... A = 8π/3 in² ≈ 8.37758 in²
Answer:
14130 yd^3
Step-by-step explanation:
The volume of a sphere is
V = 4/3 pi r^3
The diameter is 30 so the radius is d/2 = 30/2 = 15
V = 4/3 pi (15)^3
V = 4500 pi
Letting pi = 3.14
V = 14130 yd^3
we are given that
8 more than a number is greater than or equal to 0
Let's assume that number as 'x'
8 more than a number is
now, it is greater than or equal to 0
so, we can write as
now, we can solve for x
Subtract both sides 8

Answer:
2n - 5 = 7
Step-by-step explanation:
Let the number = n
Twice a number = 2n
5 less than twice a number = 2n - 5
2n - 5 = 7
