To find the area of the portion of the circle that still needs to be painted, we first need to calculate the total area of the circle and then determine how much area Kenna has already painted.
- Calculate the area of the entire circle using the formula for the area of a circle:
\[ \text{Area} = \pi r^2 \]
where \( r \) is the radius of the circle. Given that the radius \( r = 4 \) feet and using \( \pi \approx 3.14 \):
\[ \text{Area} = 3.14 \times (4^2) = 3.14 \times 16 = 50.24 \text{ square feet} \]
- Next, we calculate the area that Kenna has already painted. Since she has painted 23% of the circle, we need to find 23% of the total area:
\[ \text{Area painted} = 0.23 \times 50.24 \approx 11.55 \text{ square feet} \]
- Now, we can find the area that still needs to be painted:
\[ \text{Area left to paint} = \text{Total area} - \text{Area painted} \]
\[ \text{Area left to paint} = 50.24 - 11.55 \approx 38.69 \text{ square feet} \]
However, there seems to be an inconsistency with "23 of the circle."
If "23" refers to square feet, let's assume that it means she has painted 23 square feet so we calculate based on that:
\[ \text{Area left to paint} = \text{Total area} - \text{Area painted} \]
Assuming Kenna painted \(23\) sq ft:
\[ \text{Area left to paint} = 50.24 - 23 = 27.24 \text{ square feet} \]
Going through the options provided initially, we can reaffirm the calculation with the assumption that the originally intended area painted was \( 23 \) square feet.
Given:
- Total circle area = 50.24 sq ft
- Area painted = 23 sq ft
So, remaining = 50.24 - 23 = 27.24 sq ft
Final Answer: None of the initial choices would be accurate. The area left to paint is approximately \( 27.24 \) sq ft. However, if she painted some part of the circle designate the percentages in another manner or otherwise, let me know.
