Answer: 147 cm²
Step-by-step explanation:
Since it says to use 3 for pi, and the radius is given to us (7 cm), we will plug in and solve for the area.
A = πr²
A = (3)(7)²
A = 147 cm²
The equation would be:
3.50 + 0.15x
x represents each 'late day'
Answer:
10ft
Step-by-step explanation:
volume= 502ft³
or, πr²h = 502 ft³
or, h= 502/ (4²π)
or, h= 9.98~10ft
Sin^2 + cos^2 = 1
so,
(x/4)^2 + (y/4)^2 = 1
we got rid of t.
