2. An empty ice cream cone has a height of 3.02 inches and a radius

ololo11 [35]

Answer:

Approximate volume of ice cream = 3.03 inches

Step-by-step explanation:

Given - An empty ice cream cone has a height of 3.02 inches and a radius

of 0.98 inches.

To find - What is the approximate volume of ice cream it will hold within the cone ?

Proof -

We know that,

Volume of the cone = $\frac{1}{3}\pi r^{2}h$

where

r is the radius of the cone

h is the height of the cone

Here,

Given that,

r = 0.98 inches

h = 3.02 inches

So,

Volume = $\frac{1}{3}\pi r^{2}h$

= $\frac{1}{3}(3.14) (0.98)^{2}(3.02)$ ( Consider the value of $\pi$ = 3.14)

= 3.0373

∴ we get

Approximate volume of ice cream = 3.03 inches

So,

The correct option is - G. 3 in 3

(30 points, will mark as brainliest) I need help with my algebra 1 homework, its open book so don't worry I can ask on here.

vichka [17]

Answer:

Step-by-step explanation:

y=kx

8=-4k

k=-2

so y=-2x

$eq.~of~line~is~y-4=\frac{4-4}{1+3} =\frac{0}{4} =0\\or~y=4\\or~y=0 x+4$

eq. of line is y-5=4(x+2)

AJ is the bisector of ∠HJI. Determine the value of x.

atroni [7]

Answer:

Step-by-step explanation:

If x was equal to 12, 22.5 or 10 the side would be too large compared to 15. This is only correct if the drawing is to scale, however.

Is this a linear function?

Artemon [7]

Answer:

Step-by-step explanation:

Because a linear function is the form as

$f(x)=ax+b$

the highest exponent is one

and the graph is a line in the case of

$p(x)=3x^2-4$

is a parabola, not a line
