  • <em>area of the whole circle = r^2 times pi</em>
  • radius is 10 units
  • thus, the whole circle's area is 100pi square units.

...and this shape is exactly one quarter, one-fourth, of the whole circle.  <em>Why? because of the shape's right angle and radius. (when you multiply 90 times 4, it will equal 360 degrees, which is the angle of a whole circle.)</em>

so 100pi divided by 4 equals 25pi square units of the shape.

ANSWER:

25 pi square units

(or in decimals: multiply 25 by 3.14 which would be 78.5 square units)

2 1/4(4x-1)=1 3/5(1+4x)?? I need help with this problem. Thanks!!

Solving 2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x) we get x=\frac{77}{52}

Step-by-step explanation:

We need to solve the problem: 2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x)

Solving:

2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x)\\\frac{9}{4}(4x-1)=\frac{8}{5}(1+4x)\\9x-\frac{9}{4}=\frac{8}{5}+\frac{32x}{5}

Add 9/4 on both sides:

9x-\frac{9}{4}+\frac{9}{4}=\frac{8}{5}+\frac{32x}{5}+\frac{9}{4}

9x=\frac{8}{5}+\frac{9}{4}+\frac{32x}{5}\\9x-\frac{32x}{5}=\frac{8}{5}+\frac{9}{4}\\\frac{9x*5-32x}{5}=\frac{8*4+9*5}{20}\\\frac{45x-32x}{5}=\frac{32+45}{20}\\\frac{13x}{5}=\frac{77}{20}\\x=\frac{77}{20}\times \frac{5}{13}\\x=\frac{77}{4*13}\\x=\frac{77}{52}

So, Solving 2\frac{1}{4}(4x-1)=1\frac{3}{5}(1+4x) we get x=\frac{77}{52}
