Answer:
133.96 meters squared
Step-by-step explanation:
To calculate the area of a circle, simply multiply the radius squared, by pi.
A = pi x r^2
A = pi x 6.53^2
A = pi x 42.6409
A = 133.9603382
The area of the circle is approximately 133.96 meters squared.
Hope this helps! :)
I hope that 2-1 means 21.
DE + EF = DF
4x + 10 + 21 = 9x - 15
4x + 31 = 9x - 15
31 = 9x - 4x - 15
31 = 5x - 15
46 = 5x
x = 9 1/5 = 9.2
You want 9x - 15
9*9.2 - 15
82.8 - 15
67.8 <<<<< answer.
If I have given the wrong meaning to 2-1 (which could mean 1) leave another note and I will correct my work.
Answer:
234
Step-by-step explanation:
The exponential function that can be used to model this is f(x) = 120 * (1.1)ˣ.
f(7) = 120 * 1.1⁷ = 234
Answer:
x = 9
Step-by-step explanation:
So lets substitute, so the equation is;
14x + 4(7) = 154
Next, lets distribute;
14x + 28 = 154
Subtract 28 from both sides
14x = 126
Divide both sides by 14
x = 9
