Answer:
The area of this plate is 
.
Step-by-step explanation:
We have,
Circumference of a circular plate, C = 21.4 inches
The circumference of a circular shape is given by :
r is radius of circular shape
Area of this plate is given by :
So, the area of this plate is .
9514 1404 393
Answer:
30.25π square inches
Step-by-step explanation:
You can use the formula for area in terms of circumference:
A = C²/(4π)
A = (11π)²/(4π) = (121/4)π = 30.25π . . . square inches
_____
You may be expected to find the radius first:
C = 2πr ⇒ r = C/(2π) = 11π/(2π) = 5.5 . . . inches
Then use the area formula:
A = πr² = π(5.5 in)² = 30.25π in²
Answer:
B
Step-by-step explanation:
This is because 1/2 down from 1 1/2 is 1 then go 2 down on the number lone and you get 1 (B)
Answer:
since I don't know how many tickets they already have, I'm going to divide 1 million by 4 and say that they need to sell 250,000 tickets a month
Step-by-step explanation:
10x^2 - y + 12 - 3x^2
10x^2 - 3x^2
When you see a number that look almost the same you add or subtract
10x^2 - 3x^2
Always carry the symbol in front of the number
