Martina used 3 as the value of pi to estimate the area of a circular patio that had a diameter of 26 ft.
1 answer:
Answer:
507 ft²
Step-by-step explanation:
the area (A) of a circle is calculated as
A = πr² ( r is the radius )
given diameter = 26 then r = 26 ÷ 2 = 13 , so
A = π × 13² ≈ 3 × 169 = 507 ft²

0.426 = 426/1000 = 213/500
This would be the equation:
Y= 5/2x+5
I hope I've helped!
The circumference when the diameter is 18 = 18pi
The circumference when the diameter is 6 = 6pi
18pi/6pi=3
The circumference will become a third of what it was.
Hope this helps!
It would be 3.25 because you can’t round 0.001 up
The slope of the line is zero.
