The equation for a circle's area is 
.
We can use this equation to end up with A=(3.14)4
And 3.14 times 4 is 12.56.
Then we have to round to the nearest tenth.
Therefore your answer is 12.6

Answer:
x=-5
Step-by-step explanation:
Answer:
2.1 * 10 ^3
Step-by-step explanation:
5.67 * 10 ^7 ÷2.7 x 10^4
Divide the numbers
5.67 / 2.7 =2.1
Divide the exponents
10^7 / 10 ^4
Remember when dividing power, we subtract the exponents
10 ^(7-4) = 10^3
Put this back together
2.1 * 10 ^3
Verify that this is in scientific notation
Since this is in scientific notation, we are done
I think 100% profit means she got the gloves for free so all her revenue was profit. That can't be right. Let's assume 'profit on the cost' means a 100% markup, meaning she sold the gloves for £8.
That means she sold the skirt for £40.
She made 20% profit on the total cost t so
1.2 t = 48
t = 48/1.2 = 40
Since she spent £4 on the gloves that means she spent £36 on the skirt she sold for £40.
So she made £4 on a cost of £36 for a percentage of 1/9=.11111...
Answer: 11.1%
