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

Find the total surface area of this cone. leave your answer in terms of pi R=3 L=4

Yuliya22 [10]

Answer:

total surface area of cone is πr (r+l)

22/7 x 3 (3+4)

22/7*3 (7)

22 x 3 ( as 7 that was divided by 22 was cut out with 7 in the bracket)

hence,

TSA of cone = 66pi
