Answer:

Step-by-step explanation:

Since the y coordinates are the same the distance is found by looking at the x coordinates

6 - -3

6+3

The distance is 9 units

PLEASE HELP!

Wittaler [7]

Answer:

See below

Step-by-step explanation:

Use the formulae directly

For a cone, with base radius = r and height = h, here are the related formula

$\textrm{Slant height l} = \sqrt{r^2 + h^2}$ (1)

$\textrm{Lateral surface area} = \pi r l$

$\textrm {Base area} = \pi r^2$

$\textrm { Total Surface Area SA} = \textrm{Base Area + Lateral Area} = \pi r^2 + \pi rl = \pi r(r + l)$ (2)

$\textrm{Volume V = } (1/3) \pi r^2h$ (3)

Therefore directly plugging in the numbers in the above equations:

Note:

l = slant height in cm
SA = total surface area in sqcm
V = Volume in cubic cm

Figure(a)

r = 4, h = 8

$\textrm{l} = \sqrt{4^2 + 8^2} =\sqrt{80} = 8.944 \\\textrm{SA} = 4\pi(4 + 8.944) = 4\pi(12.944) = 162.66\\\textrm{V} = (1/3)\pi(4^2)(8) = 134.04$

Figure(b)

r = 7, h =15

$\textrm{l} = \sqrt{7^2 + 15^2} =\sqrt{274} = 16.55$

$\textrm{SA} = 7\pi(7 + 16.55) = 517.89$

Figure (c)

r = 5, l = 8

$h = \sqrt{l^2 - r^2} = \sqrt{8^2 - 5^2} = \sqrt{39} = 6.245\\SA = \textrm{SA} = 5\pi(5 + 8) = 204.2\\V = (1/3)\pi(5^2)(6.245) = 163.5$

Round 9.24 to nearest hundrer

Elanso [62]

Answer:

9.24

Step-by-step explanation:

Integer Part: 9

Fractional Part: 240

If the last digit in the fractional part of 9.240 is less than 5, then simply remove the last the digit of the fractional part.

So 9.24 rounded to the nearest hundredth is:

9.24

Is 16 and 40 relatively prime?

8_murik_8 [283]

Answer:

Step-by-step explanation:

Relatively prime means that the only common factor the 2 numbers share is 1

factors of 16 are 1, 2, 4, 8, 16

factors of 40 are 1, 2, 4, 5, 8, 10, 20, 40

common factors are 1, 2, 4, 8

Hence 16 and 40 are not relatively prime
