Answer:
Answer:18+4.5
Step-by-step explanation:
This shape is a triangle with a semicircle connected to it
and this triangle is a right triangle so side A=B
that means the other leg is 6.Knowing that we can solve
The formula for the area of a triangle is (base×height)÷2
so that means 6×6 equals 36 and if you divide that by 2 you get the 18.
Now we will deal with the semicircle. We know that both of the legs are 6 so that means the diameter is 6 and now we solve 6 divided by 2 equals 3 and we will have to square that and we will 9 and since it is a semicircle we have to divide it by 2 and that will give us 4.5 and since we have to express it in terms of pi it will be 4.5(pi) and then we add both of the areas
giving us 18+4.5(pi)

Answer:
28 Students
Step-by-step explanation:
Let's break down all of our variables.
likes strawberry
likes chocolate
7 likes vanilla
First we need to combine the number of students that like strawberry and chocolate.
This then tells us that the 7 kids that like vanilla are the remaining of the class.
Let's use ratio to find out how many students there are in total.
Let x = number of student in Mrs. B's class.
We need to multiply 4 to 7 and x to 1.
So that leave us with:
x = 28
There are 28 students total in Mrs. B's class.
