Victor measured a circular lid and found d, the diameter, was 8 inches and c, the circumference was 25 inches.

Answers

Answer 1

Answer:

If you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14.

Step-by-step explanation:

The formula for working out the circumference of a circle is:

Circumference of circle = π x Diameter of circle

This is typically written as C = πd. This tells us that the circumference of the circle is three “and a bit” times as long as the diameter."

Answer 2

And we also know that circumference C =25 inches and the formula for this circumference is given by:

We want to find the value of and solving from the last equation we got:

And replacing we got:

So then the approximation for the value of and that's very close to the real value of
Step-by-step explanation:
For this case we know that the diameter d =8 in. And we can find the radius from this info since d = 2r with r representing the radius. If we solve for r we got:

And we also know that circumference C =25 inches and the formula for this circumference is given by:

We want to find the value of and solving from the last equation we got:

And replacing we got:

So then the approximation for the value of and that's very close to the real value of

What is the length of the hypotenuse of the triangle?

Answers

Step-by-step explanation:

Hey there!

Here;

ABC is a Right angled triangle.

Taking reference angle as angleA.

Now;

Hypotenuse (h) = AB

Perpendicular (BC)= 24 ft.

Base(AC)= 10 ft.

Now, Using Pythagoras relation;

[tex]h = \sqrt{ {p}^{2} + {b}^{2} } [/tex]

Put all values.

[tex]h = \sqrt{ {24}^{2} + {10}^{2} } [/tex]

Simplify it.

[tex]h = \sqrt{576 + 100} [/tex]

[tex]h = \sqrt{676} [/tex]

Therefore, h= 26ft.

A submarine is exploring the Pacific Ocean. At 502.5 feet below sea level, the water temperature is 63 1/4°F. The submarine dives down 115 feet deeper, and the water temperature drops by 2 1/5°F. What were the elevation and the water temperature after the submarine dove? Assume that sea level is at 0 feet of elevation.

Write the submarine’s initial elevation as a rational number.

Answers

Answer:

-502.5 - 115 = - 617.5

63 1/4 - 2 1/5 =

63 - 2 = 61

1/4 - 1/5 = 5/20 - 4/20 = 1/20

so 63 1/4 - 2 1/5 = 61 1/20

after the sub dove, elevation level is - 617.5 and temp is 61 1/20 F

-502.5-115=617.......
