Answer:

$a = \pi {r}^{2}$

The radius is half of the diameter. Therefore the radius is 23÷2 = 11.5.

$a = 3.14 \times {11.5}^{2}$

$a = 3.14 \times 132.25 \\ = 415.265$

To the nearest tenth = 415.3

Rzqust [24]

Answer:

x=12

Step-by-step explanation:

For the given situation , a quantity x is added to $\frac{1}{4} x$ gives 15.

We can set up equation as

$x+\frac{1}{4}x=15$

Multiply each term by 4 on both sides to get rid the denominator.

It gives,

4 x+x=60

Now, combine like terms

5 x=60

Divide both sides by 5

x=12.
