Check the picture below.
Make sure your calculator is in Degree mode.
X + 9 = 11 doesn’t belong
x = 3 in all the other equations
8a
TSA = 2πrh + 2<span>πr^2
</span>TSA = 471 + 157 (or 150π + 50π)
TSA = 628 cm^2 (or 200π)
8b
628 x $3 = $1884
cost = $1884
8c.
V = πr^2h = π 5^ 5 (15) = 375π (or 1177.5 if use π = 3.14)
