HURRY I WILL GIVE BRAINLIEST!!
nika2105 [10]
Hi there! 

The formula for the volume of a cone is V = 1/3(pi x r^2 x h). Using this formula, we can solve for the volume of the cone.

WORK:
V = 1/3(3.14 x 6.5^2 x 14)
V = 1857.31 / 3
V = 619.10 cm^3

ANSWER:
A) 619.10cm^3

Hope this helps!! :)

A car is traveling down a highway at a constant speed, described by the equation d=65t, where d represents the distance, in mile
Alexxx [7]

Answer:

Step-by-step explanation:

We are given an equation d = 65 t, where d represents the distance, in miles, that the car travels at this speed in t hours.

We know distance, speed and time relation

d = s * t.

Where  d represents the distance, that the car travels at this speed in t  at the speed s.

If we compare that relation with the given equation, we can see s = 65.

So,

a) The 65 tell us speed of 65 miles per hour in this situation.

b) Second part seems to be incorrect. Please check it again.

c) We are given distance = 26 miles.

Plugging d= 26 in the given equation.

26 = 65 t

Dividing both sides by 65, we get

26/65 = t

t= 0.4 hours.

So, it takes 0.4 hours or 0.4 * 60 = 24 minutes o travel 26 miles at this speed.

Parallel, intersecting or skew?
const2013 [10]

Two lines are:

  • Parallel if they don't intersect and lie on the same plane
  • Intersecting if...well, they intersect at one point
  • Skew if they don't intersect and they lie on two different planes

So, we have:

  • AB and BC intersect at point B
  • AE and BF don't intersect, but both lie on the plane AEFB
  • EF and AD don't intersect and don't lie on a common plane
  • ABC and ABF intersect on segment AB
  • AED and BFC are parallel (they're both perpendicular to plane ABC)
