Answer: $\bold{C)\ 15\sqrt2}$

Step-by-step explanation:

Simply each radical (groups of two factors on the side, make one factor on the outside). Then add the like terms (same radical).

$\sqrt{8}+\sqrt{98}+\sqrt{72}\\\\=\sqrt{2\cdot 2\cdot 2}+\sqrt{2\cdot 7\cdot 7}+\sqrt{2\cdot 6\cdot 6}\\\\=2\sqrt{2}+7\sqrt{2}+6\sqrt{2}\\\\=(2+7+6)\sqrt2\\\\=15\sqrt2$

What is the radius of a sphere if its surface area is 2,122.64 square inches? (Use 3.14 for π.) 11 in. 13 in. 121 in. 169 in.

crimeas [40]

To solve this, we are going to use the surface are of a sphere formula: $A=4 \pi r^2$
where
$A$ is the surface area of the sphere
$r$ is the radius of the sphere

We know for our problem that $A=2122.64$ and $\pi =3.14$ , so lets replace those vales in our formula:
$A=4 \pi r^2$
$2122.64=4(3.14)r^2$
$2122.64=12.56r^2$
Now, we just need to solve our equation for $r$ :
$\frac{2122.64}{12.56} =r^2$
$r^2=\frac{2122.64}{12.56}$
$r^2=169$
$r=+or- \sqrt{169}$
$r=13$ or $r=13$
Since the radius of a sphere cannot be a negative number, $r=13$ .

We can conclude that the radius of a sphere with surface area 2,122.64 $in^2$ is 13 in.

Which is greater 192 inches or 5yards and 1 foot

makvit [3.9K]

1 yard = 36 inches. We have 5 yards, so 5x36 = 180

1 foot = 12 inches.

So the base 192 is largest.
