Step-by-step explanation:
Use pythgaros therom
Do 7^2 - 3^2 = 40
Do square root of 40 which equals the answer
Two column proofs are organized into statement and reason columns. Each statement must be justified in the reason column. The
reason column will typically include "given", vocabulary definitions, and theorems.
Therefore, w<span>hat can be used as a reason in a two-column proof are:

1. The volume of a cylinder equals the (area of the base)*height = ¶r2h =18.8
<span>2. The volume of a sphere can be found by the formula: </span>
<span>volume=4/3¶r3 = 33.51 </span>
<span>The volume of a cylinder equals the (area of the base)*height = ¶r2h = 150.8 </span>
<span>Therefore, 184.3 = 33.5 + 150.8 </span>

<span>4. 1st = 2 * 25 * (6/12) = 25 cf </span>
<span>2nd = 25 cf </span>
<span>3rd = 4 * 25 *(6/12) = 50 cf </span>
<span>4th = (3.14 *7.5^2/4) * (6/12) = 22 cf </span>

Answer: 76%
Step-by-step explanation:
In the first square, all 25 parts are shaded.
In another sqaure, 13 out of 25 qual parts are shaded.
Now, in both the squares
Total parts = 25+25 =50
Total shaded parts = 25+13 = 38
The percent of shaded area =
Hence, 76% is represented by the shaded area.
