Answer: question 5 is C
Question 4 is 37.68
Question 3 is 153.86 ft sq
The question about finding the area with a diameter of 16mm is 803.84
The next one is A. 25÷8
Step-by-step explanation:
C = 2 pi r
C = 2 pi (7.8) and you get 49.01
Becuse the question is asking to round c is the best choice
When using the formula of C = 2 pi r, since radius is half of the diameter, 12÷2=6
The formula for this one is A = pi r sq
You have the radius for this one is 7
Put 7 into that and you get. ~153.94
The total amount Aisha would pay to paint her room is $54.
<h3>What is the cost of painting the rooms?</h3>
The first step is to determine the area of the walls. The walls have the shape of a rectangle. Thus, the formula for the area of a rectangle would be used to determine the area of the wall.
Area of the three walls without a door : 3 x (length x width)
3 x (2.4 x 5.2) = 37.44 m²
Area of the fourth wall with a door : area of the wall - area of the door
(2.4 x 5.2) - (2 x 0.8) = 10.88m²
Total area of the walls : area of the three walls + area of the wall with the door
10.88m² + 37.44 m² = 48.32 m²
The next step is to determine the number of tins that would be needed:
48.32 /12 = 4.03
5 tins would needed
Cost of the 5 tins: (4 x 12) + (0.5 x 12) = $54
