Answer:
A ≈ 530 cm²
Step-by-step explanation:
The swept area equals the total area covered by the blade minus the unswept area.
The area of a sector with radius r and angle θ is:
A = (θ / 360) πr²
So the swept area is:
A = (θ / 360) πR² − (θ / 360) πr²
A = (θ / 360) π (R² − r²)
A = (150 / 360) π (21² − 6²)
A ≈ 530 cm²
1 and 2 are both rational.
3 and 4 are both not.
Answer:
Step-by-step explanation:
Let number of pounds of cans collected by Amy = 
Let number of pounds of cans collected by Bruce = 
Let number of pounds of cans collected by Carlos = 
As per question statement, total number of cans collected = 168
..... (1)
Number of pounds collected by Bruce is 
rd of the pounds of cans collected by Carlos.
Number of pounds collected by Amy is equal to number of pounds collected by Bruce and Carlos combined.
Using equation (2):
Using equations (2) and (3) in equation (1), we get:
Using equation (2):
To answer your question, I need to know the radius or diameter and the height of the object
Answer:
point lies on circle
Step-by-step explanation:
Substitute the coordinates of the point into the left side of the equation and if equal to the right side then point lies on circle.
(4 - 1)² + (2 + 2)² = 3² + 4² = 9 + 16 = 25 = right side
Then point (4, 2 ) lies on the circle
