Find the area of a circle with a diameter of 4.

Mathematics
1 answer:
spin [16.1K]3 years ago
5 0
The formula for area of a circle is (pi)*radius^2

Radius is half of diameter so the radius is 2.
2 squared is 4, then multiply by pi to get an answer of 4(pi) or 12.56.

Citrus2011 [14]

In this question, we want to compare several numbers with different denominators and find out which number is the least. To compare this number, we have to change the denominator into the same number by finding the least common multiple (LCM) of the 4 numbers. The factor of each number will be:

3= 3 ^1

5= 5^1

8= 2 * 2 * 2 = 2^3

2= 2^1

We can find the LCM by multiplying a higher exponent of each prime number. The LCM will be:3^1 * 5^1 * 2^3 = 120

Each number will be:

Tiger= 2/3 * 40/40= 80/120

Redbird = 4/5 * 24/24= 96/120

Bulldogs = 3/8 * 15/15 = 45/120

Titans = 1/2 * 60/60 = 60/120

As you can see, the team with the lowest chance to play is Bulldogs = 45/120

Jlenok [28]
$187.52 is 6.24% off of 200 and the amount saved is $12.48. If this is not what you meant let me know. The math is $200 × (1 - 6.24) = $187.52. Hope this helps!

Work out the shaded area​
Dennis_Churaev [7]

Answer:

<h2> 70 {cm}^{2}</h2>

Step-by-step explanation:

Shaded area:

Area of big rectangle - Area of small rectangle

= 10 \times 12 - (10 - 5) \times (12 - 2)

Calculate the difference

= 10  \times 12 - 5 \times 10

Calculate the product

= 120 - 50

Calculate the difference

= 70 \:  {cm}^{2}

Hope this helps...

I don't get it <br>i need help!!

"help..." said the high schooler.
"No," said Life, "figure it out yourself."
Then the rejected high schooler went to watch YouTube to relieve stress, hour and hours passed by until the high schooler realized he was wasting time.
"Oh no!" He said, "I have wasted time again! How will I ever get pass high school?"
"We will help you," said the flash cards, colored pens, and highlighters "we will be your best friend."
After that day, the high schooler never had an all nighter for the rest of high school. (College is a different story)

Moral of the story: Life and cute cat videos will not help you and your homework. Paying attention in class, making flash cards, making your notes colorful with pens and highlighter are what really helps :) 

Oh and asking your teacher for help is great too.

What is the volume olf the basketball the diameter is 9.5 round to mearest whole nu!mber<br>​
Novosadov [1.4K]

Answer:

143π in³

Step-by-step explanation:

A basketball has the shape of a sphere

Volume of a basketball = 4/3πr³

Diameter = 9.5 in

Radius = diameter/2

= 9.5/2

= 4.75 in

Volume of a basketball = 4/3πr³

= 4/3 * π * 4.75³

= 4/3 * π * 107.17

= (4*π*107.17) / 3

= 428.68π / 3

= 142.89π in³

Approximately

143π in³ to the nearest whole number
