What is the area of a square?A square is a four sided quadrilateral with all of the side having equal lengths. The total internal angle of a square is 360° with each side perpendicular to each other.
A square is a 4 sided polygon where all the sides are of equal length.
The area of the square is the square of any one of its side
Let a be the side of the square
Area of the square = a²
Given data ,
Let the area of the square be represented as A
Now , the value of A is
a = 6 sides
Length of one side = 2 cm
So , total length of one side = 2 x 6 = 12 cm
Now , area of square = ( 12 )² = 144 cm²
And , the area of shaded portion A = area of square - area of triangle
Area of triangle = ( 1/2 ) ( 12 ) ( 12 )
Area of triangle = 72 cm²
Now , A = 144 - 72
A = 72 cm²
Hence , the area is A = 72 cm²

Find the area of the semicircle. Round your answer to the nearest hundredth.
Answers
Answer:
56.52
Step-by-step explanation:
This is because in order to find an area of a circle you must do R^2*3.14 and since it is a semicircle add /2 so R^2*3.14/2 and since half of 12 is 6, 6*6 is 36 and 36*3.14 is 113.04 and divide that by 2 which is 56.52
Answer:
177.475 [tex]inches^{2}[/tex]
Step-by-step explanation:
Since the formula for finding the area of a full circle is A = π[tex]r^{2}[/tex], area equals pi times radius squared, we fill out the formula and solve.
A: unknown
Pi: 3.14
Radius: diameter is 12, so you divide it by 2, which is 6.
A = 3.14 x 6 squared.
using pemdas, you do exponents first,
A = 3.14 x 36
A ≈ 113.04
Now that we have the area for the full circle, we divide it by two to find the area of the semicircle,
113.04/2
= 56.52
So, the area of the semicircle is 56.52 [tex]inches^{2}[/tex]

Alrighty so your gonna start with finding the area of the rectangular prism so 4cm*3cm*12.5cm= 150 cm squared
(Rectangular prism formula is Length*Width*Height)
Then we’re gonna get the triangular prisms area. The formula for it is the same as the rectangular one but once u did it ur gonna divide it in half since a rectangle is made up of 2 triangles!
4cm*3cm*12.5= 150cm then divide it in half to get 75cm squared.
Now just add your rectangular prisms are and your triangular prisms area 150cm+75cm= 225cm squared!

What was the percent change in the average cost of a gallon of gas in 2014? Round to the nearest percent.
Answers
The percentage change of the gas will be 45%.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that the average cost of a gallon of gas in January 2014 was $3.42, and was $2.36 in December 2014.
The percentage change will be calculated as,
Percentage change = ( 3.42 - 2.36 ) / 2.36
Percentage change = ( 1.06 / 2.36 )
Percentage change = 0.45 x 100
Percentage change = 45%

A class contains 12 female and 20 male students. Find the probability that when two students are chosen randomly from the class, the first student is male and the second student is female.
Write the probability as a fraction in the simplest form.
Answers
Answer:
15 / 62
Step-by-step explanation:
Since there 32 students, of which 20 are male, the probability of selecting a student and them being male first is 20/32.
The probability of selecting another student and they are female is 12/31, because the male student is counted out of the selection because he is already picked.
This makes the probability 20/32 x 12/31 = 15 / 62
