Find the area of a circle whose radius is 14 inches. (use π = 3.1416.) a. 43.9824 square inches b. 615.7536 square inches c. 87.9648 inches d. 615.7536 inches

The area of a circle whose radius is 14 inches is:

We know that the area of a circle or some other figure is the region which is enclosed by the circle or some other figure.

The area of a circle with given radius 'r' is given by the formula:

Area of circle=πr²

where π is a irrational number whose value we have to take as:

         π = 3.1416

Here we have the radius of circle as: 14 inches.

i.e. r= 14 inches

and hence the area of circle is calculated as follows:

      Hence, the correct answer is:

           Option: B

the answer is d

step-by-step explanation:

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°

hope this
