If the circumference of the circle is 37.68 units, what is the area? (Use 3.14 for pi .)
solniwko [45]

Answer: 113.04

Step-by-step explanation: The equation for the area of a circle is pi r squared so you have to find the radius first. To find the radius, find the diameter first. A way to do this which was easiest for me was dividing 37.68 by pi (3.14), which is 12. Divide the diameter by 2 to find the radius, 6.

Now use the equation from the beginning, pi r squared. So plug in pi as 3.14, then the radius as 6. It is important to always square the radius first, which would be 36. Now multiply 36 by 3.14, and there should be your answer.

Find the area of the figure. Round to the nearest tenth if necessary.
baherus [9]

Hello!


First of all, let's find the triangle. As we can see, it is eight units long and four units tall. We can use the triangle formula and half the product.


4(8)=32

32/2=16


Now we need to find the area of the semicircle. We can use circle formulas and half our final answer. We will find the area using A=\pir².


We know that the diameter of this circle is eight. Therefore our radius is 4.


A=4\pi²

A=16\pi


Now we multiply.


16\pi≈50.27


Now we add our triangle.


50.27+16=66.27


The nearest answer to this is B)66.2. It may have been a bit over as we used \pi, not 3.14.


I hope this helps!

Using Pythagorean theorem

\\ \sf\longmapsto P^2=H^2-B^2

\\ \sf\longmapsto P^2=6^2-5^2

\\ \sf\longmapsto P^2=36-25

\\ \sf\longmapsto P^2=11

\\ \sf\longmapsto P=3.2

Find the length of the missing side. <br><br> 1) 52 cm<br> 2) 42cm<br> 3) 25 cm<br> 4) 48 cm
padilas [110]

Answer:

52 cm

Step-by-step explanation:

Use the pythagorean theorem to solve for missing sides in a right triangle.

20²+48²= missing side

20²+48²=2704

Take the square root of 2704 to get the missing side.

\sqrt{2704 } = 52
