Calculate the circumference and then add the 1 cm overlap:
C = pi*(6.6 cm) + 1 cm = 21.7 cm.
Next, mult this C by the height, 8.8 cm: Total area is 21.7 cm times 8.8 cm,
or 191.3 cm^3 (answer)
y=ax+b
->a= positive (the line is going up)
->to find a, we move one unit horizontally and look over how many units you meet the graph (1 to right, 4 up) so the a= 4
-> to find b, we look for the y-coordinate of the point where the graph and the y-axis cross. they cross in (0,1) so b is 1
when we take this all together we get y=4x+1
V=T(125) because Ik I am right
4^3/2 or 5^3/2
Anything with 3/2 in the exponent
