ed out to be 15.7079632679 so I know that’s not the correct answer.

1. First, we need to approximate <em>the radius</em>. That is the distance from that middle point to the edge. The broom is about half the distance. That means that the radius is about <em>10 feet</em>. Also, multiplying the radius by π will get you nowhere. To find the area, you need to use the equation <em>A = πr²</em>. We know know that r = 10, so 10²π ≈ 100 * 3.1 = 310 ft².

2. Complementary angles <em>add up to 90°, which forms a right angle</em>. Supplementary angles <em>add up to 180°, which forms a straight angle, or a line</em>. We can ignore A and B, since there isn't any right angles. Also, ∠RVS makes a straight line with ∠SVT and ∠RVU. From our options, we can see that C has the fitting description.

Answer:

34)310

25)option 3

Step-by-step explanation:

to find the area of a circle use the formula  pi*r^2

since 2 times the rake equals the radius

5*2=10

now use the are formula:

3.14*10^2=

314

the closest answer to 314 is 310

35) angle svt is obtuse and angle rvs appears acute

supplementary angles=180

and an obtuse angle can't be complementary as complementary angles=90

all other options are wrong since they either follow vertical angle theorem or

are complementary when they should be supplementary and vice versa

hope this helps!

Answer: B. (4x^2 + 20x)/(6x^2+x-2)

Division is the opposite of multiplication, so you just take 4x and multiply by x + 5, over 2x - 1 times 3x + 2, which is B.
