Answer:

\huge\boxed{C\approx125.6}

Step-by-step explanation:

The formula of a circumference of a circle:

C=d\pi=2\pi r

<em>d</em><em> - diameter</em>

<em>r</em><em> - radius</em>

We have the radius <em>r = 20</em>.

Substitute:

C=2\pi(20)=40\pi

use π ≈ 3.14

C\approx(40)(3.14)=125.6

I’ll award you brainliest if you answer This question

Answer:

$2353 at 12.5% and $7647 at 8.25%

Step-by-step explanation:

I'll say a is the amount he invested in one market, and b is the amount in the other.

a + b = 10000, or b = 10000 - a

multiplying the investments with the percentages and adding them together will give the total earned interest.

(a × 0.125) + (b × 0.0825) = 925

0.125a + 0.0825b = 925

Use substitution to solve for a.

0.125a + 0.0825(10000 - a) = 925

0.125 a + 825 - 0.0825a = 925

0.0425a = 100

a = 2352.94

Use substitution to find b

b = 10000 - 2352.94

b = 7647.06

The questions are to the nearest dollar so round a and b.

$2353 and $7647
