Answer:
One rose bush = $3
One bunch of ornamental grass = $4
Step-by-step explanation:
We can set up a system of equations to solve for this. Let cost of 1 rose bush be r and cost of 1 ornamental grass be g. Thus we can form 2 equations:
We can multiply the first equation by -2 so that we can eliminate g. Thus, we have:
Thus, 1 rose bush is $3. Now plugging in r = 3 into the first original equation, we can solve for g:
Thus, 1 bunch of ornamental grass is $4.
8*8 - 4*4*pi*(1/2) = 64 - 8*pi
Answer:
For the circle with the diameter of 7cm, the <u>area is about 38.48cm</u> and the <u>circumference is about 22cm</u>
For the circle with the diameter of 5cm, the <u>area is about 19.63cm</u> and the <u>circumference is about 15.7cm</u>
Step-by-step explanation:
The formula to find the area of a circle is pi*r^2
The formula to find the circumference is 2*pi*r
r = radius, which can be determined simply by taking the diameter, and dividing it by 2.
