Answer:

706.8583

Step-by-step explanation:

Area = \pi r^2

Area = \pi 15^2

Area = \pi 225

Area = 3.14159265*225

Area = 706.85834625

Round it and you get 706.8583

Find the perimeter of the triangle defined by the coordinates (7, 1), (-6, 1), and (10, 6). (Round to nearest tenth)
matrenka [14]

Answer:

35.6\ units

Step-by-step explanation:

we know that

The perimeter of triangle is equal to the sum of the length of the three sides

Let

A(7, 1), B(-6, 1), C(10, 6)

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

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

Find the distance AB

A(7, 1), B(-6, 1)

substitute in the formula

d=\sqrt{(1-1)^{2}+(-6-7)^{2}}

d=\sqrt{(0)^{2}+(-13)^{2}}

dAB=13\ units

Find the distance BC

B(-6, 1), C(10, 6)

substitute in the formula

d=\sqrt{(6-1)^{2}+(10+6)^{2}}

d=\sqrt{(5)^{2}+(16)^{2}}

dBC=16.8\ units

Find the distance AC

A(7, 1), C(10, 6)

substitute in the formula

d=\sqrt{(6-1)^{2}+(10-7)^{2}}

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

dAC=5.8\ units

Find the perimeter

P=dAB+dBC+dAC

P=13+16.8+5.8=35.6\ units

Calcule o valor numérico da expressão a seguir -2/3+1-3/2.8/9​
Zolol [24]

Answer:

The calculated value is "0.214"

Step-by-step explanation:

Given expression :

\bold {\frac{-2}{3}+ 1 -\frac{3}{\frac{2.8}{9}} }\\

solution:

\Rightarrow \frac{-2}{3}+ 1 -\frac{3}{\frac{2.8}{9}}\\\\\Rightarrow \frac{-2}{3}+ 1 -\frac{3}{\frac{2.8}{\frac{9}{1}}}\\\\\Rightarrow \frac{-2}{3}+ 1 -\frac{3}{2.8} \times \frac{1}{9}}}\\\\\Rightarrow \frac{-2}{3}+ 1 -\frac{1}{8.4}\\\\\Rightarrow \frac{-16.8 + 25.2- 3}{25.2}\\\\\Rightarrow \frac{5.4}{25.2}\\\\\Rightarrow 0.214
