360° (a circle) = 2pi radians, so 720×2pi/360
= 2×2pi = 4pi
4pi = a*pi
a = 4

kow [346]

Answer:

Option A.

Step-by-step explanation:

Area of a square is

$A=x^2$ .... (1)

where, x is side length.

The length of each side of his square plot is decreasing at the constant rate of 2 feet/year.

$\dfrac{dx}{dt}=2$

It is given that bob currently owns 250,000 square feet of land.

Fist find the length of each side.

$A=250000$

$x^2=250000$

Taking square root on both sides.

$x=500$

Differentiate with respect to t.

$\dfrac{dA}{dt}=2x\dfrac{dx}{dt}$

Substitute x=500 and $\frac{dx}{dt}=2$ in the above equation.

$\dfrac{dA}{dt}=2(500)(2)$

$\dfrac{dA}{dt}=2000$

Farmer bob is losing 2,000 square feet of land per year.

Therefore, the correct option is A.

Answer:

Angle B: 180-135=45° - supplementary angle rule

Angle C: 180-45-70=65° - sum of interior angles of triangle is 180

Angle D= Angle B : 45° - Alternate interior angles

Angel E=Angle A: 70° - Alternate interior angle.

Angle F: 180-Angle E(70) = 110° - supplementary angle rule
