Answer:
V≈75.4
Step-by-step explanation:
V=πr^2h/3
v=3.14(3)^2(8)/3=75.4
Answer:
f(x)=x+2 Passes through
x-y=2 DOES NOT pass through
Step-by-step explanation:
Method- plug in x and see if the y matches the points. (1,3) (7,9)
f(x)=x+2
f(1)=1+2=3
f(7)=7+2=9
Matches!
x-y=2
1-y=2 --> y=-1
Does not match
Answers:
Option (B) and Option (C)
Explanation:
The volume of a 3D shape is the amount required to 'fill' the figure.
"around" would be perimeter, and "outside" would be surface area.
Going from question one, 120 cubes fit the prism. This means that the prism is 120 units³.
Extra note:
Volume is measured in cubic units, not square units, like the question stated.
The central angle measure of the sector is 4.19 rad.
<h3>Area of a Sector</h3>
You need apply the formula: for finding the area of the sector, in radians. In this formula, the variables are:
r= radius
= central angle
The question gives:
A=54 cm²
r= radius= 9cm
Thus, the central angle will be:
For =3.14159..., you have :
