Iput 20 points idk how much u will get but

Area of circle = 25.12 inches²

Step-by-step explanation:

Area of circle = π × r²

Area of circle = 3.14 × 8 ( We are given the diameter not the radius )

Area of circle = 25.12 inches²

answer:   14

step-by-step explanation:          

pu you stank bo u ugly bo lol

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
