Area of pool = 2 x area of sector + 2 x area of triangle
Area of sector = \frac{ \theta}{2 \pi }  \times \pi r^2=\frac{ 2.21}{2}  \times 30^2 =1.105  \times 900=994.5 \ square \ feet
Area of triangle = 1/2 bh = 1/2 x 20 x 25 = 250 square feet

Area of pool = 2(994.5) + 2(250) = 1,989 + 500 = 2,489 square feet = 2,490 square feet.

sleet_krkn [62]

Answer:

213 euros per month

x=\frac{0.7306*3500}{1} = 2,557.1 euros

She will pay 2,557.1  euros per year.

Dividing between the 12 months of the year:

\frac{2,557.1}{12}=213.1

Rounding to the nearest whole euro she will pay 213 euros per month.

If you know that a < b, and both a and b are positive numbers, then what must be true about the relationship between the oppo
Ymorist [56]

Answer:

The number further left on a number line is the smaller number. For positive numbers, the number closest to zero is smaller. For negative numbers, the number closest to zero is larger. If a is less than b, and they are both positive, then a is closer to 0 than b. The opposite of a is also closer to zero than the opposite of b, so the opposite of a must be larger than the opposite of b.
