Answer: Choice C) 41.13 square meters

---------------------------------------------------------------------------------------------

This figure is a composition of two quarter-circles and a square

Area of quarter circle = (1/4)*(area of circle)
Area of quarter circle = (1/4)*(pi*r^2)
Area of quarter circle = (1/4)*(pi*4^2)
Area of quarter circle = (1/4)*(pi*16)
Area of quarter circle = (1/4)*16*pi
Area of quarter circle = 4pi
There are two quarter circles, so the two circular areas add to 4pi+4pi = 8pi

Area of square = s*s = 4*4 = 16 square meters

Add the square area to the circular area: 8pi+16

Now use a calculator to find 8pi+16 = 41.1327412287183 which rounds to 41.13

Answer:

t=-9

Step-by-step explanation:

2(2t-3)=6(t+2)

4t-6=6t+12

4t-6t=12+6

jonny [76]

Answer:

The number of possible choices of my team and the opponents team is

$\left\begin{array}{ccc}n-1\\E\\n=1\end{array}\right i^{3}$

Step-by-step explanation:

selecting the first team from n people we have $\left(\begin{array}{ccc}n\\1\\\end{array}\right) = n$ possibility and choosing second team from the rest of n-1 people we have $\left(\begin{array}{ccc}n-1\\1\\\end{array}\right) = n-1$
