Answer:

A = 121π in²

Step-by-step explanation:

The circumference (C) of a circle is

C = 2πr ( r is the radius )

Here C = 22π , that is

2πr = 22π ( divide both sides by 2π )

r = \frac{22\pi }{2\pi } = 11

The area (A) of a circle is

A = πr² = π × 11² = 121π in²

10 + (2^2 + 3^2) x 2<br><br><br> PEMDAS
yarga [219]
The answer would be 36.

Following PEMDAS, you'd solve what's in the parenthesis first. 2^2 = 4 and 3^2 = 9. This leaves you with 10 + (4 + 9) x 2. Add 9 and 4 to get 13, and then the parenthesis are done.

Next, you'd multiple 13 and 2 (since it's the next step in PEMDAS) to get 26.

Finally, you add together 10 and 26 to get the answer, which is 36.

I hope this helps!

I will mark brainly, help me with this question please.​
Anna [14]

Step-by-step explanation:

Since x varies directly as \sqrt{y} we can write the relation as

x = k\sqrt{y}

where k is the constant of proportionality.

a) To solve for the k, we substitute the given values:

5 = k\sqrt{13} = k(13)

\Rightarrow k = \dfrac{5}{13}

b) The equation relation x and y can be written as

x = \dfrac{5}{13}\sqrt{y}

c) When y = 9,

x = \dfrac{5}{13}\sqrt{9} = \dfrac{5}{13}(3) = \dfrac{15}{13}

Anna11 [10]
If X is the weight of the package in pounds:

1.24x + 2.49 = 11.17
1.24x = 8.68
x = 7

The package weighs exactly 7 pounds.
