Hello!

The formula for area of a circle is \pi  r^{2}

\pi is 3.14 (which is 22/7), and r stand for the radius, which is half of the diameter. If the diameter is 28 cm, the radius is 14 cm.

\pi 14^{2}
\pi (196)
616

Answer:
Approximately 616 cm^{2}.

AB = 10 in; AD = 6 in <br><br> A= <br><br> 30sqrt3 in2<br> 30 in2<br> 60 in2
Ratling [72]

Answer: 30

Step-by-step explanation:

If we were to draw diagonal BD, then we would create two congruent triangles, and we could find the area of each using the formula A=\frac{1}{2} ab \sin C.

However, since there are two triangles, we can double this, giving us A=ab \sin C.

So, the area is A=(10)(6)(\sin 30^{\circ})=\boxed{30}

Sonya has 12 cup box of ceral she wants to pour the cereal into small 1/4 cup snake how many bags of cereal will she have
malfutka [58]

Answer:

a - 48

Step-by-step explanation:

12 cups are divided into 1/4 cup bags.

Converting 12 into a fraction, you get:

12/1 divided by 1/4.

When we divide fractions, we flip the second fraction and change the operation to multiplication.

12/1 * 4/1.

Since 12/1 and 4/1 are now just whole numbers, (12 and 4), we can multiply them together.

12 * 4 = 48.
