what is the area of a semi circle when the diameter is 6
Answers
Answer: 14.13
Step-by-step explanation:
Your answer is 14.13
First, the formula for area of a semi circle is 3.14 x r^2 and divide by two.
To find the radius, we need to divide the diameter by two, which is 3.
So like
3.14 x 3^2/2
3.14 x 9/2
28.26/2
A=14.13
Answer:
14.13
Step-by-step explanation:
normal circle area equation = r^2*3.14
6/2=3
3*3*3.14
= 28.26
it's a semicircle so /2
=14.13

No, it's not because 6 x 4 = 24 and 2 x 3 = 6.
Step-by-step explanation:
In order for it to be equivalent, the simplified ratio needs to be multiplied by the same number, meaning because 6 x 4 = 24, the next number needs to be the product of 2 x 4, not 2 x 3.

24:6 is equivalent to 6:2 because 6 times 4 is 24 and 2 times 3 is 6

There are 52 weeks in a year. if Mr.Dan runs 9 miles every week, how many miles will he run in a year
Answers
Answer:
468 miles
Step-by-step explanation:
You have to multiply 52 by 9 and you get 468
Step-by-step explanation:
9 miles every week. and that for 52 weeks.
how do we calculate how many miles that are ?
well, one basic approach is
9 miles
9 miles
9 miles
... 52 times adding 9 miles.
in math we have a shortcut for that : we multiply. the hint is already in the "times" expression. we take 9 miles 52 times.
9 × 52 = 468 miles
Pls Someone help me I don't understand math very well can someone help me on how to get the answer for 1/4 x 8 4/9?
Answers
Answer:
2 4/36
Step-by-step explanation:
To do this, multiply the whole number by the denominator and add it to the numerator.
8 x 9 = 72
72 + 4 = 76
76/9
Then multiply across (multiply numerators with numerators; denominators with denominators)
76 x 1 = 76
9 x 4 = 36
76/36 = 2 4/36
____________________________
A faster way to do this is to multiply the whole number by the fraction and then the fraction by the fraction.
1/4 x 8/1 = 8/4 = 2
1/4 x 4/9 = 4/36
= 2 4/36
Answer:
2 1/9
Step-by-step explanation:
Multiplying fractions: Numerator times numerator over denominator times denominator. IF you have a mixed number, convert it into improper fraction, then do numerator times numerator over denominator times denominator.
1/4 x 76/9 (I got 76/9 because the 8 means 8 9/9s, so (8 x 9)=72 plus 4 because 4/9s=76/9)
1/4 x 76/9= 76/36
=38/18
=19/9
=2 1/9

Solve for x. 12(x+11) = 24
Answers
Answer:
x = -9
Step-by-step explanation:
First, divide both sides by 12 to isolate the expression, x + 11
12(x + 11)/12 = 24/12
x + 11 = 2
Then, subtract 11 from both sides
x + 11 = 2
- 11 - 11
x = -9
So first, you are going to distribute.
12x+132=24
Now, subtract 132 from both sides of the equation.
12x+132=24
-132 -132
After you do that, you should end up with..
12x= -108
Now you can then divide both sides of the equation by the same term!
12x= -108
——- ——-

Answer:
Range=88°−30°=58°F
