What is the value of t?

inna [77]

Answer:

4.56

Step-by-step explanation:

After this equation is simplified, it is solved the way any 1-step linear equation is solved.

1.4t -0.4(t -3.1) = 5.8 . . . . . . given

1.4t -0.4t +1.24 = 5.8 . . . . . eliminate parentheses

t +1.24 = 5.8 . . . . . . . . . collect terms (now you have a 1-step equation)

t = 4.56 . . . . . . . . . .subtract 1.24

A cone has a radius of 3 and a height given by the expression 2a. Which expression represents the volume of the cone?

DiKsa [7]

V=(1/3)hπr^2 where h=height and r=radius
given
radius=3
height=2a

r=3
h=2a

v=(1/3)hπr^2
v=(1/3)(2a)π(3)^2
v=(1/3)2aπ9
v=6aπ

so the expression would be some variaant of v=6aπ

sebuah topi berbentuk kerucut dengan panjang diameter 18 cm dan tinggi topi tersebut 20cm berapakah volume nya

madreJ [45]

Answer:

The area of the cone is "1,695.6 cm³".

Step-by-step explanation:

The given values are:

Diameter of cone,

d = 18 cm

then,

Radius,

r = $\frac{d}{2}$

= $\frac{18}{2}$

= $9 \ cm$

Height,

h = 20 cm

As we know,

⇒ Area of a cone = $\frac{1}{3} \pi r^2 h$

On substituting the given values in the above formula, we get

⇒ = $\frac{1}{3}\times 3.14\times (9)^2\times 20$

⇒ = $\frac{1}{3}\times 3.14\times 81\times 20$

⇒ = $3.14\times 27\times 20$

⇒ = $1,695.6 \ cm^3$
