You can see the fountain is made of 2 semicircles. You can apply the same area formula to both. The fourth circle has a fourth of the area of a circle. Add all 3 areas to get the fountain's area. Since the circumference of a circle is it's perimeter, find the circumference of all of the circles and add them up. THE sums is the fountain's perimeter.
Answer:
The expression for the total cost is C=5x+4y
Step-by-step explanation:
step one:
given that the total number of Hats bought is
5
the total number of T-shirt bought is 4
step two:
let the cost of Hat be x
and also the cost of the T-shirt be y
also, let the total cost be C
step three:
the total cost of all hats and t-shirts is given as
C=5x+4y
