Answer: 1661 cm^2
Step-by-step explanation:
The area of a circle is pi*radius^2.
The diameter is given as 46 cm and the radius is 1/2 of the diameter = 23 cm.
Therefore, the area of the circle is pi*23^2 = 529pi = about 1661 cm^2

Step-by-step explanation:
You didn't give the options but let me help out.
Timothy purchased $11.25 worth of groceries and paid $12.15 after taxes on Monday.
We would solve this using direct proportion.
y = kx.
12.15 = 11.25k
k = 12.15 / 11.25
k = 1.08
Timothy paid $59.13 after taxes on a purchase of groceries that cost $54.75 on Friday.
y = kx.
59.13 = 54.75k
k = 59.13 / 54.75
k = 1.08
The equation that models the relationship will be:
y = 1.08x
