What is the height of the cylinder given v=904.78 cm^3 and r =6 cm ^2

1 answer:

7 0

V = (pi)r^2 * h
V / (pi)r^2 = h
V = 904.78
r = 6

904.78 / (3.14 * 6^2) = h
904.78 / (3.14 * 36) = h
904.78 / 113.04 = h
8.004 rounds to 8 = h........height is 8 cm

Find the mean of this data set: {– 78, -12, 3, – 44}

blagie [28]

Answer:

Answer: A. -32.75

$\dashrightarrow{ \tt{mean = \frac{ \sum f(n)}{n} }} \\$

• f(n) are the values of the set

• n is the number of items

$\dashrightarrow \: { \tt{mean = \frac{ - 78 + ( - 12) + 3 + ( - 44)}{4} }} \\ \\ \dashrightarrow \: { \tt{ \frac{ - 131}{4} }} \\ \\ \dashrightarrow \: { \boxed{ \tt{mean = - 32.75}}}$
