Answer: $1267.18yd^2$

Step-by-step explanation:

$Formula: \pi r(r+\sqrt{h^2+r^2} )$

We need;

$\pi = 3.14\\r=?\\h=18yd$

We don't have the radius, but we do have the diameter. A diameter is twice the radius. Therefore, we can divide the diameter by 2 in order to obtain the radius.

$\frac{d}{2}= \frac{24}{2}=12yd$

Now plug this info into the formula.

$(3.14)(12yd)[(12yd)+\sqrt{(18yd)^2+(12yd)^2} ]$

Let's solve the square root first.

$(3.14)(12yd)[(12yd)+\sqrt{324yd^2+144yd^2} ]$

$(3.14)(12yd)[(12yd)+\sqrt{468yd^2} ]$

$(3.14)(12yd)[(12yd)+\sqrt{468yd^2} ]\\(3.14)(12yd)(12yd+21.63yd)$

Now solve the sum

$(3.14)(12yd)(33.63yd)\\$

Multiply

$1267.18yd^2$

A ball is thrown into the air The height, h in feet, of the ball can be modeled by the equation h=-16t^2+20t+6, where t is the t

Lina20 [59]

The ball will take $\frac{5}{8}$ seconds to reach its maximum height.
The maximum height is $12 \frac{1}{4}$ feet.

Elizabeth made an English muffin pizza using 1/4 cup of cheese and 3/8 cup of sausage. How many cups of toppings did she use?

Sonbull [250]

Answer: The answer is $\dfrac{5}{8}~\textup{cups}.$

Step-by-step explanation: Given that Elizabeth made an English muffin pizza by adding the following quantities of cheese and sausage..

Cups of cheese used by Elizabeth is given by

$C_c=\dfrac{1}{4}~\textup{cups}.$

And cups of sausage used by Elizabeth is given by

$C_s=\dfrac{3}{8}~\textup{cups}.$

Therefore, total number of cups of toppings used by Elizabeth is

$C=C_c+C_s=\dfrac{1}{4}+\dfrac{3}{8}=\dfrac{5}{8}~\textup{cups}.$

Thus, the number cups of toppings used is $\dfrac{5}{8}~\textup{cups}.$
