can someone help me with this please?? its due today and i only have an hour to finish. im failing math right now and i really need to get my grade up before monday

the answers is 1

Step-by-step explanation:

C = 18π cm

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Geometry

Circumference Formula: C = 2πr

Step-by-step explanation:

Step 1: Define

Identify variables

r = 9 cm

Step 2: Find C

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 c, not positive though
