The formula for the circumference of a circle with diameter d is. c = πd b. The circumference of a circle is 8 inches. What is the diameter of the circle?

c. The circumference of a circle is 6π inches. What is the radius of the circle?

The diameter of the circle is 2.54 inches

The radius of the other circle is 3 inches.

Step-by-step explanation: if the circumference is given, Diameter is C/π so 8/3.14 is about 2.54

If the circumference is 6π, the radius is 6π/2π =3

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

i think it is 70
