Answer:
Area of semicircle = 226.08 in²
Step-by-step explanation:
Diameter of semicircle = 24 in
We need to find area of semicircle.
The formula used to find area of semicircle is:
First we will find radius
We know that: radius = diameter/2 = 24/2 = 12
Now, finding area
So, Area of semicircle = 226.08 in²
Answer:
The area of the living room and hallway together = 437ft²
Question:
The complete question related to the one above found at 'Geometry in class' is stated below:
Abbey is getting new carpet in her living room and hallway.
The following diagram shows the two together.
If = 38 ft, b = 15 ft, c = 19 ft, and d = 19 ft, what is the area of the living room and hallway together?
Find attached the diagram of the question.
Step-by-step explanation:
To determine the area of the living room and hallway together, we would break the diagram into two rectangles.
Calculate the area of each and sum the two outcomes together.
Find attached the diagrams of the solution.
Given: a = 38 ft, b = 15 ft, c = 19 ft, and d = 19 ft,
Area of rectangle = length × breadth
Area of rectangle 1 = a × (d-b)
= 38 × (19-15) = 38× 4
Area of rectangle 1 = 152ft²
Area of rectangle 2 = c × b
= 19 × 15 = 285
Area of rectangle 2 = 285ft²
The area of the living room and hallway together = Area of rectangle 1 + Area of rectangle 2
= 152ft² + 285ft²
The area of the living room and hallway together = 437ft²
All quadrilaterals should have 360 degrees.
Answer:
The temperature on the 5th day was of -9ºC.
Step-by-step explanation:
Mean of a data-set
The mean of a data-set is the sum of all values in the data-set divided by the number of values.
The mean temperature for the first 4 days in January was 1°C.
This means that during the first 4 days, the sum of the temperatures was 4*1 = 4ºC.
The mean temperature for the first 5 days in January was -1°C.
First 4 days: Sum of 4º
5th day: Temperature of x.
The mean is -1, so:
The temperature on the 5th day was of -9ºC.
