Find the arc length of the semicircle?
myrzilka [38]

Answer:

The length of the semicircle arc is 6π

Step-by-step explanation:

To solve this problem we need to use the circumferenc formula of a circle:

c = circumference

r = radius = 12

π = pi

c = π * d

we replace with the known values

c = π * 12

c = 12π

The length of the circumference is 12π

N ow we divide the circumference by 2 and we will obtain the length of the arc of the semicircle

12π / 2 = 6π

The length of the semicircle arc is 6π

1. Sarah's current account balance is $2,600. She made a single lump sum amount of
ziro4ka [17]

Answer:

The simple interest that said investment yielded was 3.75% per year.

Step-by-step explanation:

Given that Sarah's current account balance is $ 2,600, and she made a single lump sum amount of $ 2,000 eight years ago into the account, to calculate the equivalent simple interest rate (quoted annually) that she earned the following calculation must be performed:

(2,600 - 2,000) / 8 = X

600/8 = X

75 = X

2,000 = 100

75 = X

75 x 100 / 2,000 = X

7,500 / 2,000 = X

3.75 = X

Thus, the simple interest that said investment yielded was 3.75% per year.
