Answer:
multiplication
The asterisk , also called a "star," is used for a number of different purposed in mathematics. The most common usage is to denote multiplication so, for example, . When used as a superscript, the asterisk is commonly voiced " -star." A raised asterisk is used to denote the adjoint. , or sometimes the complex conjugate ...
They give the formula as:
Surface Area =<span> (2 • <span>π <span>• r²) + (2 • <span>π • r • height)</span></span></span></span>
However the 2*PI*r^2 part of the formula is used to calculate the 2 "ends" of a cylinder. Since the problem states that you are NOT to count any of surface area of the "ends" then you only need the <span>(2 • <span>π • r • height) part of the formula.
So, r = 3 inches and height = 8 * 3 inches, the side area equals
2 * PI * r * height
2 * 3.14159 * 3 * 24 =

452.39 cubic inches which is the lateral area.</span></span></span>
Hi! So, here’s what I know. Every triangle will equal to 180*. So to check if that triangles is 180 we add all angles and it should add up to 180*.
Now the question is, Why it shows that the angles of a triangle equal to 180* when added up?
Note that we see all angles lie on a straight line, therefore we know that when we add angles that lie on a straight line it will equal to 180*, they will also meet at the same point.
This is all I can help with. Hope it helped something!!! Have a great day!
Answer:
21 cm
Step-by-step explanation:
2 sides of a triangle must equal to more than the last side of the triangle. So, 6 + 15 is more than 6 cm, also more than 8 cm, and also more than 18 cm. So the answer must be 21 cm. I hope this helped and please mark me brainliest!
