Answer:

Step-by-step explanation:
Given
Shape: Opening of a circular vase


Required
Determine the area
This opening implies a circle; hence the area will be calculated using area of a circle.

Solve for radius (r)



Substitute 6.75 for r in 


--- Approximated
1 times 10^1=10
1 times 10^-1=1/10
1 times 10^-2=1/100
1 ten thousandth is 1/10,000, that is 1 times 10^-4
answer is
1*10⁻⁴
Answer:
c = 7
Step-by-step explanation:
Given
2x + y = c
Since (3, 1) is on the line then it makes the equation true,
Substitute x = 3, y = 1 into the equation
2(3) + 1 = c
6 + 1 = c
7 = c
The answer should be 39/400
