Remember the formula of the area of a circle is:
$V = \pi * r^{2}$
SO given that
V = 226.98
and $\pi = 3.14$
Plug in a chug
226.98 = 3.14 * $r^{2}$
$r^{2}= 72.287$
r = 8.50

Remember that d = 2 * r
d = 2 * 8.5 = 17

Perform the indicated operation.(3/a+2) + (4/a-5)

kipiarov [429]

Answer:

$\frac{7(a-1)}{(a+2)(a-5)}$

Step-by-step explanation:

To solve this operation we need to find the common multiple of both denominators and solve for a.

$\frac{3}{a+2} + \frac{4}{a-5} =\frac{3(a-5)+4(a+2)}{(a+2)(a-5)} =\frac{3a-15+4a+8}{(a+2)(a-5)} =\frac{7a-7}{(a+2)(a-5)} =\frac{7(a-1)}{(a+2)(a-5)}$

Thus, the solution is 7(a -1) / (a+2)(a-5)

Simplify the following expression completely using distribution and combining like terms

LiRa [457]

$\huge \boxed{\mathbb{QUESTION} \downarrow}$

Simplify ⇨ 19m + 14 - 3 (3m + 7)

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

$\sf \: 19 m - 14 - 3 ( 3 m + 7 )$

Use the distributive property to multiply -3 by 3m+7.

$\sf \: 19m-14-9m-21$

Combine 19m and -9m to get 10m.

$\sf \: 10m-14-21$

Subtract 21 from -14 to get -35.

$\boxed{\boxed{\bf \: 10m-35 }}$
