Answer:
4021.2 cm³
Step-by-step explanation:
you start by getting the radius, the radius is half the diameter which in this case half of 16 is 8 so 8 is your radius and you already know the height which is 20, now that we have the radius and the height we can start
the formula for finding the volume of a cylinder is πr² · h
so are formula would be π8² · 20 which turns into π64 · 20 which then turns into 1280π or 4021.238...
which you then said we need to round the nearest tenth so 4021.238 to the nearest tenth is 4021.2 cm³
Let A = 4 A=4 A=4 cm and B = 9 c m B=9
cm B=9cm. The distance between A A A
and B B B is the absolute value of their
difference: IA-BI=B-Al=14-9..
Answer:
see explanation
Step-by-step explanation:
Given
9
- 225
← factor out 9 from each term
= 9( - 25 ) ← difference of squares
Difference of squares factors in general as
a² - b² = (a - b)(a + b)
= (x² )² ⇒ a = x²
25 = (5
)² ⇒ b = 5
Hence
- 25
= ( -5 )( + 5 )
Thus
9 - 225
= 9 ( - 5 )( + 5 )
Answer:
32units
Step-by-step Explanation :
Area of rectangle = length × Width
x = 8 × 4
x = 32
Answer:
b) 1000x + 115
Step-by-step explanation:
C = 20y + 15
= 20(50x + 5) + 15
= 1000x + 100 + 15
= 1000x + 115
