Answer: Attached.
Step-by-step explanation:
Either solve the equations directly, or graph them and look for the point of intersection.
Answer:
The area of the circle is 28.26
The area of the circle in terms of pi is 9π
Step-by-step explanation:
radius = half of diameter
d = 6
r = 6/2 = 3
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 3
π = pi
a = π * r²
we replace with the known values
a = π * (3)²
a = π * 9
a = 9π
The area of the circle in terms of pi is 9π
9 * 3.14 = 28.26
The area of the circle is 28.26
Answer:
the answer is 8
Step-by-step explanation:
cube root of 512 is 8
40% = 40 / 100 = 0.4
32 is 40% of what
= 32 / 40
= 32 / 0.4
= 80

U can also use this equation to solve it.
32 = 40%x
Simplfy
= 32 = 2/5x
Flib the equation.
2/5x = 32
Multipy both sides by 5/2
(5/2) * 2/5x = (5/2) * 32
x = 80.
