The radius of a semicircle is 3 feet. What is the semicircle's area? Use 3.14 for Pi

valentinak56 [21]

Answer:

14.13 ft²

Step-by-step explanation:

The area of a semicircle is

$= \frac{\pi \: {r}^{2} }{2}$

We were given the radius of the semicircle to be: r=3 feet.

We were also asked to use π as 3.14.

We substitute into the formula to get:

$= \frac{3.14 \times {3}^{2} }{2}$

This is the same as:

$= \frac{3.14 \times 9}{2}$

$= 3.14 \times 4.5$

$= 14 .13 {ft}^{2}$

The area of the semicircle is 14.13 ft²

Write an equation that relates the number of peppers, n, and the cost, C.

SCORPION-xisa [38]

Complete Question:

The local Farm Market sells peppers at five for $2.25. Write an equation that relates the number of peppers, n, and the cost, C.

Answer:

$C = 0.45n$

Step-by-step explanation:

Given

$5\ peppers = \$2.25$

Required

Determine the relationship between C and n

$5\ peppers = \$2.25$

Divide both sides by 5, to get the cost of 1 pepper

$\frac{5\ peppers}{5} = \frac{\$2.25}{5}$

$1\ pepper = \frac{\$2.25}{5}$

$1\ pepper = \$0.45$

Multiply both sides by n to get the cost of n pepper

$n*1\ pepper = \$0.45*n$

$n\ pepper = \$0.45n$

So, we have:

$C = 0.45n$
