Find the area of this figure. Round your answer to the nearest hundredth. Use 3.14 to approximate Pi.

taurus [48]

Answer:

$26.13ft^2$

Step-by-step explanation:

Step 1 - As both triangles have lengths the same size, they both add together to equal a rectangle. Therefore:

4 x 3 = 12

Which is the area of the triangles.

Step 2 - Calculating the area of a circle uses the formula:

$\pi r^2$

Where r is the radius of the circle.

Plug the known variables in:

$\pi \cdot 3^2\\\pi \cdot 9\\3.14 \cdot 9 = 28.26\\$

However, this is the area of a full circle. The figure is only half a circle so we must divide this by two:

28.26 ÷ 2 = 14.13

Now, add the area of the semi-circle to the area of the triangles:

14.13 + 12 = 26.13

Therefore, the area of the figure is $26.13ft^2$ .

Hope this helps!

Solve in one variable<br> 2/3x + 5 = 3/2x

Montano1993 [528]

First, we group together the terms with variables in one side by subtracting 3/2 x and 5 from both sides of the equation.
(2/3)x - (3/2)x + 5 - 5 = (3/2)x - (3/2)x - 5
(-5/6)x = -5
The value of x from the equation is 6.

Aisha ate 1/4 of the carrots in the bag. Enrique ate 3/12 of the carrots in the bag. Compare the amounts of carrots they each at

Neko [114]

The amount of carrots they each ate are the same because 12 is a multiple of 4. There are 3 4’s in one 12. If you multiply 1/4 times 3 you will get 3/12 because 1 x 3 = 3. And 4 x 3 = 12

mixer [17]

Total distance is 132 miles x 2 times/day x 5 days = 1320 miles
That used 4 gallons of fuel, so 1320 miles/4 gallons = 330 miles per gallon
