The area of a circle is <span>πr²
the outer circle area = </span><span>π 4x²
the inside circle area = </span>π.6²=36<span>π
</span>the outer circle area - <span>the inside circle area = </span><span>he shaded region
</span>π 4x² - 36π =<span>220π cm2 it implies x²-9 =55 and x²=64, and x =sqrt(64)=8
the value of x is 8</span>
Answer:
4.375
Step-by-step explanation:
Convert.
4 = 4.
3/8 = .375
4 + .375 = 4.375.
Switch the x and y then divide by two, then add 6 y=(x+6)/2
(7x^3 – 4x^2) + (2x^3 – 4x^2)
Add 2x^3 to 7x^3
(9x^3 - 4x^2) + (-4x^2)
Add -4x^2 to -4x^2. This would be the same as subtracting 4x^2 from -4x^2
Final Answer: 9x^3 - 8x^2
*The answer cannot be broken down anymore. It's in it's simplest form.
Answer:
158
Step-by-step explanation:
4 x 5 is 20. 73 - 20 is 53. 53 x 2 is 106, and when you add 52, you get 158
