Answer:

<em>11.72sq.m</em>

Step-by-step explanation:

Area of the shaded region = Area o triangle - Area of the semicircle

Area of triangle = 1/2 * base * height

Area of triangle = 1/2 * 6 * 6

Area of triangle = 3 * 6

Area of triangle = 18sq. m

Area of semicircle = πr²/2

r is the radius =  2m

Area of semicircle = π(2)²/2

Area of semicircle = 2(3.14)

Area of semicircle = 6.28sq. m

Area of the shaded region = 18 - 6.28

<em>Area of the shaded region = 11.72sq.m</em>

What is the distance between (-2 1/2,-3) and (1,-3
satela [25.4K]

Answer:

3\frac{1}{2}\ units

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

(-2\frac{1}{2},-3)\ and\ (1,-3)

Convert mixed number to an improper fraction

2\frac{1}{2}=\frac{2*2+1}{2}=\frac{5}{2}

so

we have

(-\frac{5}{2},-3)\ and\ (1,-3)

substitute the values in the formula

d=\sqrt{(-3+3)^{2}+(1+\frac{5}{2})^{2}}

d=\sqrt{(0)^{2}+(\frac{7}{2})^{2}}

d=\frac{7}{2}\ units

Convert to mixed number

\frac{7}{2}\ units=\frac{6}{2}+\frac{1}{2}=3\frac{1}{2}\ units
