The diameter of a circle is 1.4 centimeters. Find its area. Use 3.14 Round to the nearest

NeTakaya

Answer:

Area = 1.54

Step-by-step explanation:

Area = π $r^{2}$

π = 3.14

diameter = 1.4

radius (half of diameter) = 0.7

Area = 3.14 x $0.7^{2}$

Area = 3.14 x 0.49

Area = 1.5386

round to the nearest hundredth:

1.5386 = 1.54

the volume of the cylinder is 572.27 cm³

Explanation:

Given:

radius of the cylinder = 4.5cm

height = 9cm

To get the volume of the cylinder, we will use the formula:

$\begin{gathered} Volume\text{ = \pi r^^b2h} \\ where\text{ \pi= 3.14} \\ r\text{ = radius, h = height} \end{gathered}$ $\begin{gathered} Volume\text{ of the cylinder = 3.14 }\times\text{ 4.5}^2\text{ }\times\text{ 9} \\ Volume\text{ of the cylinder = 3.14 }\times\text{ 182.25} \\ \\ Volume\text{ of the cylinder = 572.265 cm}^3 \end{gathered}$

To the nearest hundredth, the volume of the cylinder is 572.27 cm³

each question for y=3 points

since she then needs a total score of more than 93 to pass, we add up total correct questions and
