Find the area of the semicircle. Round your answer to the nearest hundredth. PLEASEE HELPP

trapecia [35]

Answer:

Area of semicircle = 226.08 in²

Step-by-step explanation:

Diameter of semicircle = 24 in

We need to find area of semicircle.

The formula used to find area of semicircle is: $Area=\frac{\pi r^2}{2}$

First we will find radius

We know that: radius = diameter/2 = 24/2 = 12

Now, finding area

$Area=\frac{\pi r^2}{2}\\Area=\frac{3.14\times (12)^2}{2}\\Area=\frac{452.16}{2}\\Area=226.08\:in^2$

So, Area of semicircle = 226.08 in²

A hotel wants to put a fence around a circular spa. The radius of the spa is feet. If the fence is built along the immediate edg

MariettaO [177]

For this case we must find the perimeter of the fence, in a circular way, knowing that the perimeter of a circle is given by:

$P = 2 \pi*r$

Where "r" represents the radius of the circle, in this case $r = \frac {5} {\sqrt {2} -1}$

Substituting in the perimeter equation we have:

$P = 2 \pi * \frac {5} {\sqrt {2} -1}$

Rationalizing we have:

$P = \frac {2 \pi * 5 (\sqrt {2} +1)} {(\sqrt {2} -1) * (\sqrt {2} +1)}\\P = \frac {2 \pi*5 \sqrt {2} +2 \pi*5} {2-1}\\P = 10 \pi \sqrt {2} +10 \pi$

Taking out common factor $\pi$ :

$P = (10 \sqrt {2} +10) \pi$

Answer:

$P = (10 \sqrt {2} +10) \pi\ feet$

2(11r + 7) + 1 = 1/4 (88r+60) show the steps please i need this asap

disa [49]

2(11r + 7) + 1 = 1/4 (88r+60)
22r + 14 + 1 = 22r + 15 ---------------------->distributive property
simplify
22r + 15 = 22r + 15
0 = 0
answer: infinite solutions
