Could someone please give me the correct answer? id appreciate it

Answer: A = 198.6cm²

Step-by-step explanation: The figure includes two semi circles on both ends. These can be solved as a whole circle with a diameter of 10cm because each semi circle is 5cm.

r = 10/2= 5cm

Area of circle:

A = πr²

A = 3.142*5²

A = 3.142*25

A = 78.55

A = 78.6cm²

The remaining section of the shape is a rectangle with a length of 12cm.

To get this, you subtract 10 from 22 because each semi circle is 5cm which adds up to 10cm.

The rectangle has a width of 10cm.

Area of rectangle:

A = lw

A = 12*10 = 120cm²

The total area of the shape:

A = 120 + 78.6

A = 198.6cm²

Answer:

D. 5 inches

Step-by-step explanation:

Given:

A frozen dinner is divided into 3 sections on a circular plate with a 12-inch diameter.

That means complete angle having 360° is divided into 3 section.

The central angle formed by the peach cobbler is 105 degrees.

The central angle formed by the pasta is 203 degrees.

Question asked:

What is the approximate length of the arc of the section containing the peas?

Solution:

The central angle formed by the peas = 360° - 105° - 203°

= 52°

$Ridius,r=\frac{Dameter}{2} =\frac{12}{2} =6\ inches$

As we know:

$Length\ of\ arc=2\pi r\times\frac{\Theta }{360}$

$=2\times\frac{22}{7} \times6\times\frac{52}{360} \\ \\ =\frac{13728}{2520} \\ \\ =5.44\ inches$

Therefore, the approximate length of the arc of the section containing the peas are 5 inches.
