A homeowner is building a square fence around his circular patio so that each side of the fence is tangent to the circle, as shown in the diagram below. The radius of his patio is 18 yards. What is the perimeter of his fence?

144 yards

Step-by-step explanation:

The tangents will form a square of each side equal to the diameter.

Diameter = 2 × 18 = 36

Perimeter = 4×36 = 144 yards

144 yards

Step-by-step explanation:

Perimeter of a square (P) = 4s where s is the side length of the square

Since the fence is tangent (touching and perpendicular) to the patio, then the side length of the fence is the diameter of the circle. (See attachment)

Radius of circle = 18  ---> Diameter of circle = 2(18) = 36 ---> side length = 36

P = 4s

  = 4(36)

  = 144

It will help you understand how to put together the information you are given in order to solve for the missing information.

intensity of the vector is v= √37 ≈ 6.08 units and make angle ∡α ≈ 9.46° with east direction

step-by-step explanation:

required vector is consists of the two componentsvx= 2+4=6 units   and vy= 1 unit and vx ⊥ vywe will use pythagorian theorem to find intensity of the vector vv∧2 = vx∧2 + vy∧2 => v = √vx∧2 + vy∧2 = √6∧2 + 1∧2 = √36+1 = √37 ≈ 6.08 unitsthe angle ∡α between vector and east direction we wil find with tanαtanα = 1/6 => α = arc tanα = arc 1/6 => α ≈ 9.46°

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
