Answer:
19,27 cm^2
Step-by-step explanation:
area of triangle = (6 x 3)/ 2 = 9 cm^2
circle area : 3^2 x 3,14 = 28,27 cm^2
area of shaped region = 28,27 - 9 = 19,27 cm^2
Example: 2x + 6 < -8
There's 2 steps to solve this one.
2x + 6 < -8
Subtract 6 from both sides
2x < -14
Divide both sides by 2
x< -7
Answer:
39.13 units²
Step-by-step explanation:
Height of the triangle:
10cos(30) = 5sqrt(3)
Radius = ⅓(5sqrt(3)) = 5sqrt(3)/3
Triangle - circle
[½(10)(10)sin60] - [(3.14)(5sqrt(3)/3)²]
43.30127019 - 4.166667
39.13460352 unitsw
