Jessica has a circular birdbath in her backyard with a radius of 1.25 feet. She wants to place a decorated border around the cir

Alexxandr [17]

Answer:

The total cost is 28.26.

Step-by-step explanation:

The radius of the birdbath is 1.25 feet.

The cost per foot is 3.6 .

The formula for perimeter of circle is given by,

= 2πR , where R is the radius of circle.

Inserting the above value of radius in the equation above,

circumference = 2(π)(1.25) = 2(3.14)(1.25) = 7.85 $ft^{2}$

Thus the total cost is,

= (7.85)(3.6) = 28.26

Emma puts $10,000 in a simple interest account at a bank.

goldenfox [79]

Answer: Hi Hope This Helps :D

Step-by-step explanation:

We have to calculate the annual interest rate for the account. Formula for the simple interest is : I = P * r * t, where P is the investment, r is the annual interest rate and t is time in years. In this case: 1,800 = 10,000 * r * 4; 1,800 = 40,000 * r; r = 1,800 : 40,000; r = 0.045, or 4.5 %. Answer: The annual interest rate is 4.5 %
