Find the circumference and area of a circlewith a radius of 5 feet.​

Mathematics
1 answer:
iVinArrow [24]3 years ago
4 0

Circumference = 2(pi)r

Area = (pi)r^2

r = 5

5 * 2 = 10

Circumference = 10π

5 * 5 = 25

Area = 25π

Using 3.14 as pi substitute:

5 * 3.14 = 15.7

15.7 * 2 = 31.4

Circumference = 31.4

5 * 5 = 25

25 * 3.14 = 78.5

Area = 78.5

What is the value of x
pav-90 [236]

Let's start with triangle RST. This is a 30-60-90 triangle, which means it has the relationship x - x sqrt(3) - 2x.

If RS is 2 sqrt(3), then ST must be 2 and RT must be 4.

Triangle QRT is a 45-45-90 triangle, which means it has the relationship x - x - x sqrt(2).

If RT is 4, then RQ must also be 4.

Answer: x = 4

Hope this helps!

So the x intercepts are going to be at the places where y = 0 so you can just read that off and get (-2,0) and (3,0). Hope this helps :)

Find the volume of the following
Nadusha1986 [10]

Given:

A prism with right triangular base.

Base of triangle = 6 ft

Height of triangle = 8 ft

Height of prism = 7

To find:

The volume of the given prism.

Solution:

The volume of prism is:

V=Bh             ...(i)

Where, B is the base area and h is the height of the prism.

In the given figure, the base of the prism is a right angle triangle with legs 6 ft and 8 ft. So, the area of the base is:

B=\dfrac{1}{2}\times base\times height

B=\dfrac{1}{2}\times 6\times 8

B=\dfrac{48}{2}

B=24

Substituting B=24,\ h=7 in (i), we get

V=24\times 7

V=168

Therefore, the volume of the prism is 168 cubic ft.

Evaluate 15 − 4 + (7 − 5)2 = __________.
blagie [28]
15-4=11 plus
(7-5)= 2
if is times 2 is 32
if is plus 2 is 15
if is minus 2 is 11 
and if is divided by 2 is 6.5
 (I'm saying all that because you didn't put any symbol beside the number 2)

Using the inequity -16k-32>-48
3241004551 [841]

Answer:

k<1

Step-by-step explanation:

1. Add 32 to both sides

-16k-32+32>-48+32

2. Simplify

-16k>-16

3. Reverse the sign (You only reverse the sign if you are DIVIDING BY a negative.)

-16k/-16 = k

-16/-16 = 1

You're left with k < 1

Your number line graph should be an open circle at 1 going to the left.
