The circumference of a circle is 15 meters. Find the area. Use 3.14 for π.

What is the value of the radius rounded to the nearest tenth?
What is the approximate area of the circle rounded to the nearest tenth? m2

plz dont get mad, i tried my best

I think your answer will be  615.752 cm²

514.46 m2

Step-by-step explanation:

A = π * R² = π * 14² = 615.752 cm²

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
