Answer:
81pi mm^2
Step-by-step explanation:
The radius is 1/2 the diameter, and is used in finding the area of a circle.
The formula for this is
A = pi(r)^2
So the formula you would use is
A = pi (9)^2
= 81pi
Usually teachers accept it in terms of pi, but if not, you can use 3.14 and multiple it.
I hope this helped!
52=24 + b
to find b, you just subtract (52-24)
28 to 24 is our ratio
we can simplify this (just like fractions!) since both are even, let’s do it by 2!
28/2 = 14 and 24/2 = 12
simplify once more and you get our ANSWER: 7:6
Answer:
The correct option is B
Step-by-step explanation:
Given information: ∠F=32°,∠D=54° and DF=18m.
According to the angle sum property of triangle, the sum interior angles of a triangle is 180°.
Using angle sum property, we get





Law of sine:

Using law of sine we get




Cross multiply,

Divide both sides by 0.99756405026.


The value of EF is 14.6 m. Therefore the correct option is B.
$275*x%=195
It will be a 29% reduction. But it will not have the exact cost of $195
Answer:
g(x) = (3x - 2)(x + 4)
x = {-4, 2/3}
Step-by-step explanation:
g(x) = 3x^2 + 10x - 8
Factor
g(x) = (3x - 2)(x + 4)
Zero I
3x - 2= 0
3x = 2
x = 2/3
Zero II
x + 4 = 0
x = -4
x = {-4, 2/3}
