I don’t kno how to do any of this ...

the first one the area is 706.86. i rounded.

Step-by-step explanation:

the equation for finding the area of a circle is

the radius squared times pi. hopefully that helps you solve the rest of them!

1: 706.86

2: 95.03

3: 12.57

4: 12.57 (?) (can't see all of the question)

5: 314

Formula for circle: A=3 x r (radius) x r (radius)

Multiply the radius times itself and multiply that by three.

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

depends on how many days you are talking about
