V= 1/3 times pi times radius squared times height
V= 1/3 • 3.14 • 4.5 squared • 4(4.5 because 9 divided by 2)
V= 1/3 • 3.14 • 20.25 • 4
V= 1.0466 • 81
V= 84.7746 units cubed
If told to round to nearest tenth then 84.8 , if hundreds then 84.78
Given:
A figure of a right angle triangle.
To find:
The value of Tan R.
Solution:
Trigonometric Ratio: In a right angle triangle,

Using the above trigonometric ratio in the given triangle, we get


Therefore, the correct option is C.
Answer:
180
Step-by-step explanation:
Area of troiangle=180
A+B+C=180
22+90+B=90
112+B=180
B=180-112
B=68
perimeter=A+B+C
22+90+68=180

We are given ratio nickel to zinc to copper = 2:7:9.
From this ratio we can see that <em>ratio of nickel to zinc is 2:7</em>.
Let us assume number of pounds of nickel have to be used to create alloy that contains 4.9 lb of zinc is x pounds.
So, we can setup a proportion as :
x : 4.9 = 2:7
Or

On cross multiplication, we get
7x= 4.9× 2
7x = 9.8
Dividing both sides by 7, we get
x = 1.4.
<h3>Therefore, 1.4 pounds of nickel have to be used to create alloy that contains 4.9 lb of zinc.</h3><h3 />
