Answer:
A = 15π in²
Step-by-step explanation:
If two of the central angles are 80° and 130°, totalling 210°, then the third central angle must be (360° - 210°), or 150°.
Let's calculate the area of the entire pizza, whose diameter is 12 in and whose radius is therefore 6 in:
A = πr² → A = π(6 in)² = 36π in².
The area of the largest slice, the one with central angle 150°, is
(150/360) times the total area of the pizza:
A = (150/360)(36π) in², or 15π in²
Answer:
4 km
Step-by-step explanation:
T = time
D = distance
S = speed
the forumla to find the distance is
T * S = D
manipulate the equation for this problem:
D/S = T
Plug-in the known values
D = 12.5 km
S = 50kph
12.5km/50kph
cancel units and simplify
4 km
