Formula for the area of a quarter circle: A = (pi x r^2) / 4
A = (pi x 2^2) / 4
A = (pi x 4) / 4
A = 4pi / 4
A = 1pi = 3.14 square miles
Hope this helps! :)
Umm im pretty sure d= -3x im not to sure
Answer:
120 votes
Step-by-step explanation:
So one way to solve this is by creating an equation to solve for x.
So we are given 4/7, that will be one side of the equation.
And we are trying to figure out how many votes out of the 210 she received, so on the other side of the equation we will have x/210, since we are solving for x.
So 4/7 = x/210
We want to get x alone, so we can multiply 4/7 by 210, which equals 120.
So x equals 120!

Answer: 300</h3>
====================================================
Explanation:
One general template of exponential functions is
f(x) = a*(b)^x
The 'a' is the initial amount, which in this case is a = 300
----------------------
Extra info:
The b is the base of the exponential, which is b = 1.16
The value of b is helpful to determine if you have exponential growth or decay, and how much of either. Because b = 1.16 is greater than 1, it indicates exponential growth. The rate of growth is found by solving 1+r = 1.16 to get r = 0.16, which leads to 16% growth.
Answer:
260 cm
Step-by-step explanation:
formula for finding volume:
<u>l x w x h = v</u>
l=length w=width h=height v=volume
× 3 × 
= 
how did i do that?
cross multiply the whole number and the denominator together and add the product by the numerator.
= 
so, × × 
cross simplify(dont have to do it just makes everything easier)
and you get:
× 
× 
and you get 
= 260 cm
plz give me a brainliesttttt
