Answer:
The circle's diameter is 6cm
Step-by-step explanation:
A = 28.26 cm^2
D = ![\sqrt[2]{\frac{A}{\pi } }](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B%5Cfrac%7BA%7D%7B%5Cpi%20%7D%20%7D)
D = ![\sqrt[2]{\frac{28.26}{\pi } }](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B%5Cfrac%7B28.26%7D%7B%5Cpi%20%7D%20%7D)
D = 6cm
Let x equal the one number.
Let y equal the other number.
x + 3y = 24
5x +3y = 36
Subtract the first equation from the second equation.
4x = 12
x = 3
For the given triangles:
There are 3 pairs of congruent angles
the triangles can not be proved using the congruent angles
the congruent angles used to prove the similarity of the triangles
So, the answer will be:
For the given triangle, we can not prove they are congruent.
The slope-intercept form: y = mx + b.
m - slope, b - y-intercept

We have the points (0, 75) → y-intercept (b = 75), and (7, 40).
Substitute the coordimates of the points to the formula of a slope:

<h3>Answer: y = -5x + 75.</h3>
Answer:
90 meters squared
Step-by-step explanation:
First you multiply 10*4.5=45
Then you multiply 45 and 2 because 1cm=2m
45*2=90
