perimeter = sum of all sides
27 = 9+7.8+x
x (third side) = 10.2
Answer:
Step-by-step explanation:
You would do y2-y1 over x2-x1. In your equation, this would be -15-0 over -11-3, giving you -15 over -14
Answer:
slope = 2

work is in the picture if you need it... please mark brainiest
Answer:
Step-by-step explanation:
The area of the base is given by the formula ...
A = πr²
so the radius is ...
r = √(A/π) = √(1386/(22/7)) = √441 = 21 . . . units
__
The volume is given by ...
V = (1/3)Bh
where B is the area of the base, and h is the height (equal to the radius). Filling in the numbers, we have ...
V = (1/3)(1386)(21) = 9702 . . . . cubic units
Answer:
120°
Step-by-step explanation:
Area of a sector is:
A = πr² (θ/360°)
Plugging in values and solving:
49/3 π = π (7)² (θ/360°)
49/3 π = 49π (θ/360°)
1/3 = θ/360°
θ = 120°
