Answer:

$\pi \times 3^{2}$

Step-by-step explanation:

formula

$surface \: area = \pi \times r^{2}$

Now just solve this and you have it.

$surface \: area = \pi \times 3^{2}$

What is the answer and how do I solve it?

The lengths of the rectangles are 7 and 12 respectively. Form the ratio 7/12. The widths of the rects. are x and 5 respectively. Form the ratio x/5. Now equate these two ratios:

7 x
--- = ---
12 5

Solve this for x. One way to do this would be to cross-multiply, obtaining 12x = 35, and solving this result for x. x will be a fraction. Write the numerator and denominator in the boxes given.

A 1-liter bottle of orange juice used to cost $2.85 at a food market. Its price has increased; the new price is 110 percent of t

AfilCa [17]

Answer:

The new price of the bottle is $ 3.14.

Step-by-step explanation:

Given,

Original price of 1-liter bottle of orange juice = $ 2.85,

Since, the new price is 110 percent of the original price.

Thus, the new price of the bottle = 110 % of the $ 2.85

$=\frac{110\times 2.85}{100}$

$=\frac{313.5}{100}$

$=3.135\approx 3.14$

Hence, the new price of the bottle is $ 3.14.

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
