Answer:
The diameter of the pizza is 12 inches
Step-by-step explanation:
Given:
Circumference of a pizza = 38 inches
To Find:
The Diameter of the pizza =?
Solution:
Circumference:
The distance around the edge of a circle (or any curvy shape).
It is a type of perimeter.
We know that the shape of the pizza is circle.
So the given circumference is circumference of a circle.
Now,
Circumference of the circle(pizza)=
where r is the radius of the circle
circumference of the pizza =38
Thus
r=6.050 inches
Now,
Diameter = 
Diameter = 
Diameter=12.1 inches
Rounding to the nearest tenth
Diameter=12 inches

To find perimeter of triangles, use the formula P = a + b + c, where a, b, and c are the sides of the triangle.
For this triangle, you are given two sides and the perimeter and asked to find the third side. To do that, plug the given values into the formula for perimeter and solve.
P = a + b + c
10.8 = 3.5 + 2.6 + c
10.8 = 6.1 + c
4.7 = c
The measure of the third side of the triangle is 4.7 cm.

The perimeter of a quadrilateral is the sum of the length of its four sides. So to find the perimeter, simply add all the sides together. As you need to find a missing side, follow the same steps as above to find the missing side.
15.3 = 2.7 + 4.7 + 3.3 + x
15.3 = 10.7 + x
4.6 = x
The length of the missing side of the quadrilateral is 4.6 cm.
Answer:
y = 200·1.15^t
Step-by-step explanation:
The ratio from one year to the next is 1.15, so the balance is a geometric sequence. Since t starts at zero, we can write the balance (y) after t years as ...
Answer:
− 5 x − 16
Step-by-step explanation:
-2*x and -2*4= -2x+-8
-2x+3x= -5x
-8-8= -16
-5x-16
