Answer:

50.24 centimeters squared

The diameter (d) is 8 which means the radius is 4 (8/2)

we use the formula pi x radius^2

It says to use 3.14 for pi

so the equation is 3.14(4)^2=3.14 x 16 = 50.24

Mamont248 [21]

Answer:

S(0, 2)

Step-by-step explanation:

Midpoint Formula: $(\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2} )$

Step 1: Plug in known variables

5 = (10 + x)/2

-8 = (18 + y)/2

Step 2: Solve

10 = 10 + x

x = 0

-16 = 18 + y

y = 2

Step 3: Write coordinates

(0, 2)

Collin invested $5529 in the account paying 2% and $2171 in the account paying 9% interest.

<u>Explanation:</u>

Let x be amount invested at 2%

So, 7700 - x will be the amount invested at 9%

0.02(x) + 0.09(7800 - x) = 315

0.02x + 702 - 0.09x = 315

-0.07x = -387

x = $5529

7700 - x = 7700 - 5529

= $2171

Collin invested $5529 in the account paying 2% and $2171 in the account paying 9% interest.
