The answer is b hope this helps
solution:
we know that ,
u.v = ΙuΙ ΙvΙcosθ
here,
θ =60° (since the given triangle is equilateral triangle)
u.v = ΙuΙ ΙvΙcos60°
= 1 x 1 x 1/2
u.v = 1/2
now, u.w = ΙuΙ ΙwΙcosθ
= ΙuΙ x cos(60x2)
u.w = -1/2
Yes because the perimeter of the bulletin is 23 feet. this is because to find perimeter you use 2(L)+2(W).
Answer:
Area of given figure = 37.68 unit²
Step-by-step explanation:
Given:
Radius of given shape = 4 unit
Angle = 270°
Value of π = 3.14
Find:
Area of given figure
Computation:
Area of given figure = [Ф/360][πr²]
Area of given figure = [270/360][(3.14)(4)²]
Area of given figure = [0.75][(3.14)16]
Area of given figure = [0.75][50.24]
Area of given figure = 37.68 unit²
