Answer:
1649.33 units³
Step-by-step explanation:
Let the height and the radius be known as "h" and "r" respectively.
<u>Formulae(s):</u>
- Volume of cylinder: πr²h
- Volume of cone: πr²h/3
Clearly, we can see that the volume of the cylinder is three times greater than the volume of the cone as,
- ⇒ πr²h = 3(πr²h/3)
- ⇒ πr²h = πr²h (True)
<u>Determining the volume of the cylinder;</u>
- ⇒ Volume of cylinder = Volume of cone × 3
- ⇒ Volume of cylinder = 175π × 3
- ⇒ Volume of cylinder = 525π
- ⇒ Volume of cylinder = 1649.33 units³ (2 d.p)
Therefore, the volume of the cylinder is 1649.33 units³.
Two numbers that multiply to -240 and add to -1 are -16 and 15
-16 x 15 = -240
-16 + 15= -1

Answer:
- 
Step-by-step explanation:
Rationalise the denominator by multiplying the numerator/ denominator by the conjugate of the denominator
the conjugate of 
+ 5 is - 5, hence
12 / ( + 5) × ( - 5 ) / ( - 5)
= (12 - 60 ) / - 18
= -
