Write the volume of a cylinder with a base radius 3 m and height 8 m in terms of pi

IRISSAK [1]

Answer:

72π (in terms of pi)

Step-by-step explanation:

V = π·r²·h

Plug in the values.

V = π·3²·8

Solve.

V = 72π

To leave an equation in terms of pi, just square, multiply, and leave pi at the end.

3² = 9·8 = 72

72π

If you need the answer fully simplified, it is 226.19 (rounded up).

Sonja [21]

Answer:

$\large\boxed{C)\ 5cm}$

Step-by-step explanation:

$P=2(l+w)\\\\\text{Put}\ l=2cm\ \text{and}\ w=\dfrac{1}{2}cm\ \text{to the formula of the perimeter:}\\\\P=2\left(2+\dfrac{1}{2}\right)=(2)(2)+(2)\left(\dfrac{1}{2}\right)=4+1=5\ cm$
