A circle has a diameter of 8. What is the area in terms of π?

I need the answer asap

Answers

Answer 1

Answer:

50.24²

Step-by-step explanation:

Okay, so the formula for the area of a circle is π x radius² and we're just going to use 3.14 for π so:

We first have to find the radius, the radius is half the diameter:

8 ÷ 2 = 4

So 4 is our radius

4² = 16

3.14 x 16 = 50.24

So, the area of the circle is 50.24²

hope this helps:)

Answer 2
Area is approximately 50.27

Formulas:
A=pi r^2
D=2 r

When solving for A:

A=1/4pi d^2 = 1/4*pi*8^2 which is approximately 50.26548


ANSWER: approximately 50.27

Which relationship is a function ?

Answers

Answer:

A function is a relation in which each input has only one output. In the relation , y is a function of x, because for each input x (1, 2, 3, or 0), there is only one output y. x is not a function of y, because the input y = 3 has multiple outputs: x = 1 and x = 2.

Can someone please help me with this question the instructions are to use a calculator to find the perimeter (the solid lines and curves) of each figure. The perimeter of each semicircle can be found by using the equation 1/2 pi d (the place where I put the words pi has the pi symbol, and d is just a variable. Also use 3.14 as pi, and the top part is cut off a little bit, but it still counts as a full semi circle. Please help me.

ALEX tried to find the value of x. FIND HIS ERROR AND CORRECT IT.

Answers

it’s a 90 degree angle. So the equation so be 28+2x =90 and find x from there.


28+2x=90
-28 -28
2x= 62
x=31
His error was he put 180 rather than 90 because it’s and acute angle so the number you minus by would be 90 done and then you finish the equation like he did

Explain how you found the answer using the relationships of angles.

Answers

Answer:

∠1 - 40°

Step-by-step explanation:

∠1 - 40°

b/c it's a right triangle and we have two angles given, 50° and 90°. Add them and subtract by 180° and get 40°.

∠2 - 140°

b/c an exterior (outside) angle is equal to the two most isolated / farthest angles added. The two most is angles are 105° and 35°, add them and get 140°.

∠3 - 40°

b/c ∠'s 1 and 3 are vertical angles meaning they're equal so since ∠1 is 40°, so is ∠3.

∠4 -

b/c ∠' s 2 and 4 are vertical angles meaning they're equal so since ∠2 is 140°, so is ∠4.

∠5 - 35°

b/c we have two angles, 105° and 40°. Add them and subtract by 180° and get 35°.

21 is less than w+6 solve the inequality for w

Answers

Step-by-step explanation:

21<w+6

honestly I think im wrong because I didn't really get the question, sorry

Answer:

15 < w

Step-by-step explanation:

We are given the expression "21 is less than w + 6" and are asked to solve this inequality for "w".

To do so, we first need to create the actual inequality, if 21 is less than w + 6, then the sign we should use is the less than sign (<).

21 < w + 6

Now we solve for w, which is by isolating w :

21 < w + 6

Subtract 6 from both sides :

15 < w
