Answer:
22, 24, 26, 28, 30
Step-by-step explanation:
If the sum of 5 numbers is 130, that means the average of these numbers is 26.
If it is the average then it is the middle, or the third number. The two numbers before it would then be 22 and 24 by subtracting twos, and the two numbers after it would be 28 and 30 by adding twos.
22, 24, 26, 28, 30
Answer:
Part A) Rectangle
Part B) Triangle
Part C) Cone
Part D) Circle
Step-by-step explanation:
Part A) Perpendicular cross section of a cylinder
The perpendicular cross section of a cylinder is a rectangle
The base of the rectangle is equal top the diameter of the circular base of cylinder and the height of the rectangle is equal to the height of the cylinder
Part B) Perpendicular cross section of a pyramid
Cross sections perpendicular to the base and through the vertex of a pyramid will be triangles
Part C) Shape created when a right triangle is rotated about the y-axis
When a right triangle is rotated about the y-axis, then it forms a cone.
The vertical leg of the triangle becomes the height of the cone.
The horizontal leg of the triangle becomes the radius of the cone.
The hypotenuse of the triangle becomes the slant height
Part D) Parallel cross section of a sphere
The parallel cross section of a sphere is a circle
All cross sections of a sphere are circles
Answer:
Dnd
Step-by-step explanation:
Answer:
88.2 squared
Step-by-step explanation:
The formula to find the area of a circle is <em>a = pi * r ^2</em>
Let's replace the values that we know.
a = 3.14 x 5.3 ^2
First, we should do 5.3 ^2, which is 28.09.
a = 3.14 x 28.09
Now we are able to do 3.14 x 28.09 which is 88.2026
But that isn't it! We need to round to the nearest tenth, which is this digit:
88.<u>2</u>026
Since next to the 2 there is a 0, you take out all the numbers after that 2. Which leaves you with:
88.2
