Answer:

Radius: <u>7 cm</u>

Diameter: <u>14 cm</u>

Circumference Formula: <u>c = </u><em><u>dπ</u></em><u> or c = 2rπ</u>

Circumference Value: <u>c = 14π or c = 2(7π)</u>

Step-by-step explanation:

We are given that the <u>radius</u> of the circle is <u>7 cm</u>. The diameter will always be twice as large as the radius so that will lead us to <u>14 cm</u> as the <u>diameter</u> of the circle. The formula is quite simple. There are <u>two different types of formulas</u> for <u>finding the circumference of a circle</u>. If only the <u>diameter is given</u>, then we use the formula <u>c = </u><em><u>dπ</u></em>, where d is for diameter and π is for pi or 3.14159. If only the <u>radius is given</u>, then we use the formula <u>c = 2rπ</u>, where r is for radius and π is for pi or 3.14159. In this case, we are going to use the formula for radius since only the radius is given. Simply plug in the value for radius then multiply the radius to π or 3.14159 and multiply the product by 2 to get the circumference of the circle. If I am wrong, please let me know. I hope this helps! :D

Answer:

7cm

14cm

dπ or 2r π

14π or 2(7π)

Step-by-step explanation:

Radius = 7cm

Diameter = 7 x 2 = 14cm

Circumference = 2 x π x r = dπ

Circumference Value = 2 x π x 7 = 14π

The expressions below represent either exponential growth or exponential decay. Check all the expressions that represent exponen
asambeis [7]

Answer:

Answers B, E and F (1, 5 and 6).

Step-by-step explanation:

In an exponential equation, (y=ab^x), the "b" value must be a decimal less than 1 (but greater than 0) for it to be considered an exponential decay function. Only equations B, E and F have a "b" value that fits this criteria.

Please answer all three questions Pleaseeeeee tysmm &lt;3
oee [108]

Answer: 2 3/4 > 2.68 is correct (only)

Step-by-step explanation: 2 3/4 = 2.75, and 2.75 is greater than 2.68

The rest are incorrect. 7.895 * 10^2 (100) = 789.5, and 5.43 * 10^3 (1000) = 5430. So 789.5 > 5430 is false.

Sqrt(63) = 7.93, and 7.93 > 8.11 is false.

Absolute values ( | | ) mean that no matter if it is negative or positive, it will become positive (unless the negative sign is outside the absolute value). 1.5 > 3.2 is false, and even without the absolute value, -1.5 is still less than 3.2
