Step-by-step explanation:
Add the area if the rectangle, to the area of the two semi-circles.
Area of Rectangle: L: 6[tex]\frac{5}{8}[/tex] in times W: 8 in = 53 in
Area of Semi-circle: [tex]\frac{1}{2}[/tex](πr2): [tex]\frac{1}{2}[/tex](π(4)2) = 25.13
(r is always half of diameter (d) so r=4)
53 + 25.13 + 25.13 = 103.26

Why does the Moon appear to be the same size as the Sun during a solar eclipse?
Group of answer choices
Gravity pulls the moon closer to the Earth during a solar eclipse due to the planetary alignment so it ends up looking larger than normal.
While the moon is much smaller than the sun, the moon is also much closer to Earth so it appears larger.
The Moon Illusion occurs when the moon is in certain positions in the sky, which plays a trick on our brain to make it appear larger than it really is.

An architect is creating a scale model of a building with a rectangular base. The ratio of the
building's base length to the scale model's base length is 110 in : 3 in. If the length of the base
of the scale model is 9 inches (in), what is the length of the base of the building to the nearest
foot?
Answer:
Answer: 28
Step-by-step explanation: 110in/ 3in = L/ 9in
Since we’re solving for L we see that L= 110in/ 3in x 9in = 330in.
Since there are 12 inches in 1 foot, you can determine the number of feet in the length of the building base by dividing the total number of inches by 12.
330/12 = 27.5 which rounds to 28 feet
The length of the base of the building is approximately 27.5 feet to the nearest foot.
To find the length of the base of the building, we can set up a proportion using the given ratio and the length of the base of the scale model.
Let's denote the length of the base of the building as 'x' feet.
The ratio of the building's base length to the scale model's base length is given as:
110 in : 3 in
To convert the scale model's base length to feet, we divide it by 12:
9 in ÷ 12 = 0.75 ft
Now we can set up the proportion:
110 in / 3 in = x ft / 0.75 ft
Cross-multiplying, we have:
110 in * 0.75 ft = 3 in * x ft
82.5 ft*in = 3x ft
To solve for x, we divide both sides by 3:
82.5 ft*in / 3 = x ft
27.5 ft = x ft
Therefore, the length of the base of the building is approximately 27.5 feet to the nearest foot.
