Respuesta:
21,16cm
Explicación paso a paso:
Volumen de un cono = 1 / 3πr²h
r es el radio de la base del cono
h es la altura del cono
Dados los siguientes valores
radio r = 18,8cm
Volumen = 416,4 centímetros cúbicos
Sustituir en la fórmula y obtener la altura.
Volumen de un cono = 1 / 3πrh
416,4 = 1 / 3π (18,8) h
416,4 = 1/3 * 3,14 * 18,8 h
416,4 = 19,6773h
Intercambio
19,6773h = 416,4
h = 416,4 / 19,6773
alto = 21,16 cm
<em>Por lo tanto, el valor más grande que se puede tomar para la altura h, por lo que el volumen es un máximo de 416,4 centímetros cúbicos es </em><u><em>21,16 cm.</em></u>
Number 3 is D, number 4 is B, number 5 is B
Answer:
$120
Step-by-step explanation:
Let the initial value of bond be $X
The future value of any bond is calculated by formula
FV= PV(1+r)^n
where
- FV is future value of bond
- PV is present value of bond
- r is the rate that at which value of bond appreciate
- n is the number of years of maturity
In the problem given
FV= $146
r = 4% = 0.04 (dividing 4 by 100 we get 0.04)
n = 5
substituting these value in formula
![146 = X(1+0.04)^5\\=> X = 146/1.04^5\\=> X = 120](https://tex.z-dn.net/?f=146%20%3D%20X%281%2B0.04%29%5E5%5C%5C%3D%3E%20X%20%3D%20146%2F1.04%5E5%5C%5C%3D%3E%20X%20%3D%20120)
PV =$X = $120
Hence current value of bond is $120.
