Hola!
Circumference of circle is 12.56 cm
Means,
2 × π × r = 12.56
r = 12.56 × 3.14 × 2
r = 1.999 cm
According to Question,
Area of Circle:
π × r²
3.14 × 1.99 × 1.99
12.547 cm² = 12.56 cm² (approximately.)
Hence,
Area of Circle is 12.56 cm²
hope it helps!
polynomial of the 5th degree, with two terms.
Distribute 4x^2(–2x^2 + 5x^3) to get –8x^2 + 20x^5. Reorder in standard form 20x^5-8x^4. 5 is the highest exponent so it is the 5th degree, there are two terms because terms are separated by a plus or minus.
Add 72, 75, and 83, which equal 230. Then, since there are three values, you divide the total (230) by 3, which would equal 76.6 (cont), therefore meaning they can only raise their average (using the three tests, from a base grade of 0) to a 76.6 percent (or 77 if teacher rounds grade)
Let's make the equation.
2(N+9)=6
Let's divide both sides by 2.
n+9=3
Now subtract 9 from both sides.
n=-6
So, the number is -6.
Answer:
6
Step-by-step explanation:
We use rates to solve this so we do 28/4=7.
Using that, we know he can do 7 quizzes in 1 week.
Now 7 times 6= 42 right? so do 1 times 6.
The final answer is 6 weeks.
Hope this helps :)
