A circular plot of land has a diameter of 16 yards. What is the area of theland? Use 3.14 for it.O A. 803.84 yd2O B. 50.24 yd2O

Amiraneli [1.4K]

The area of the circle can be calculated with the following formula

$A=\pi\cdot r^2$

First let's find the radius

$\begin{gathered} r=\frac{16}{2}\text{yds} \\ r=8\text{yds} \end{gathered}$ $\begin{gathered} A=\pi\cdot8^2 \\ A=3.14\cdot64 \\ A=200.96\text{ yd2} \end{gathered}$

The answer would be 200.96 square yards

Suppose a water tank in the shape of a right circular cylinder is thirty feet high and eight feet in diameter. a) How much sheet

Zanzabum

Answer:

$755.98 ft^2$

Step-by-step explanation:

Height of the Cylinder= 30 feet

Diameter = 8 feet

Radius= Diameter/2 = 8/2 = 4 feet

The Amount of Metal Sheet used in constructing the tank is the Total Surface Area of the Tank.

Total Surface Area of a Cylinder =

$=2\pi r(r+h)\\=2*\pi*4(4+30)\\=8*\pi*30=\\=240\pi\\=755.98 ft^2$

Use the functions and the scenario to solve the problem.

Naily [24]

Answer:

Leanne is correct. It is important that g(x) is subtracted from f(x).

Shiloh is incorrect. She subtracted f(x) from g(x), and subtraction isn't commutative.

*Just took the test, got the answer correct!! Hope this helps!
