Answer:

Step-by-step explanation:

The formula is area of circle x height

To find area do radius x radius x 3.14 so 49 x 3.14 = 153.86

Since the answer already has pi just do 49 x 10 = 490

Given:

Radius,r =7cm
height ,h=10cm

To find out:

the volume of the cylinder

Formula used:

$\pi \: r {}^{2} h$

Solutions:

$volume \: of \: cyli. = \pi \times 7 \times 7 \times 10$

$volume \: of \: cylinder= \red {490\pi}$ cm²

Lillian kicks a football. Its height in feet is given by h(t)= -16t^2+72th(t)=−16t 2 +72t where tt represents the time in second

Hitman42 [59]

The after 9/4 seconds the football is at its highest point which is 81 feet if Lillian kicks a football. Its height in feet is given by h(t)= -16t²+72t

<h3>What is a parabola?</h3>

It is defined as the graph of a quadratic function that has something bowl-shaped.

$\rm h(t)= -16t^2+72t$

Making perfect square:

$\rm h(t)= -[(4t)^2-72t+9^2 -9^2]$

$\rm h(t)= -[(4t-9)^2 -81]$

$\rm h(t)= 81-(4t-9)^2$

The highest point will be when term (4t-9)² becomes zero

So the highest point = 81 feet, and it takes:

t = 9/4 seconds

Thus, the after 9/4 seconds the football is at its highest point which is 81 feet if Lillian kicks a football. Its height in feet is given by h(t)= -16t²+72t

What is the perimeter of DEFG, shown?

Murrr4er [49]

Answer:

C.34

Step-by-step explanation:

you find the length which is 10 squares and the width which is 7 squares. Since the shape is a quadrilateral you add all sides to find the perimeter= 2L+2W. 2(10)+2(7)=20+14=34
