The diameter of the circle is 5.4 cm. The shaded area is 180 degrees, which is 1/2 of the circle.

Calculate the area of the full circle and divide by 2.
Area = PI x r^2
r = 5.4/2 = 2.7

Area = 3.14 x 2.7^2 = 22.90

Area of shaded part: 22.90 / 2 = 11.45 cm^2.

The answer is A.

How do I solve this?

blagie [28]

Answer:

We'll solve that in parts.

The upper part is a right triangle that is 4 by (2 + 2 +6)

Area = (4 * 10) /2 = 20

The bottom of that figure is made of 3 parts.

A) a 2 by 2 right triangle. area equals (2*2)/2 = 2

B) a 2 by 2 square whose area equals 2*2 = 4

C) a 6 by 2 right triangle whose area equals (6*2) / 2 = 6

Total Area = 20 + 2 + 4 + 6 = 32

Which expressions are not polynomials?

Naddika [18.5K]

Answer:

The middle two expressions shown are not polynomials

Step-by-step explanation:

Polynomial terms have positive integer exponents on any variables. A 2/3 power is not an integer exponent. Division by y is equivalent to an exponent of -1, which is not a positive integer.
