Answer:56.8 inches
Step-by-step explanation:
For perimeter we must find the lengths of the 2 diagonal sides of the triangle which are the same because it is isosceles.
the triangle is cut directly in half so both halves of the base are 17/2
17/2 = 8.5
solve through pythagoren theorum
altitude^2 + (half of base)^2 = (diagonal length)^2
18^2 + (8.5)^2 = (diagonal length)^2
324 + 72.25 = (diagonal length)^2
396.3 = (diagonal length)^2
= diagonal length
diagonal length = 19.9
diagonal length + diagonal length + base = perimeter
19.9 + 19.9 + 17 = perimeter
56.8 inches = perimeter
Answer: The volume of the cone is 130 cubic centimeters.
Step-by-step explanation:
We know that to find the volume of a cylinder you will use the formula
V= 
Where r is the radius and h is the height.
And to find the volume of a cone you will use the formula
V= 
*h /3
So if they have the same dimensions which is the height and the radius then we will just divide the volume of the cylinder by 3 to find the volume of the cone.
V = 390/3
V = 130 cm^3
of students only saw jewelry collection
<em><u>Solution:</u></em>
Given that, On a class trip to the museum,5/8 of the students saw the dinosaurs
7/8 of the students saw either the jewelry collection or the dinosaurs
<em><u>To find: Fraction of students only saw jewelry collection</u></em>
From given statement,
Fraction of students saw dinosaur = 
Fraction of students saw either the jewelry collection or the dinosaurs = 
Therefore,
Fraction of students only saw jewelry collection = Fraction of students saw either the jewelry collection or the dinosaurs - Fraction of students saw dinosaur

Thus
of students only saw jewelry collection
