A circle has an area of 36 m2. What is the area of a 40 sector of this circle?

ruslelena [56]

The ratio of the area of the sector (S) to the area of the entire circle (C) is equal to the ratio of the angle subtended to form the sector (As) to the angle for the whole revolution (Ac)
S / C = As / Ac
Substituting the given,
S / 36 m² = 40 degrees / 360 degrees
Solving for S gives, S = 4. Thus, the area of the sector is 4 m².

An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. The drain pipe can be used to empty the pool in 34 ho

Talja [164]

<u>Answer: </u>

An inlet pipe on a swimming pool can be used to fill the pool in 33 hours. Time it will take to fill the pool = 748 hrs

<u>Solution: </u>

Let x = time it will take to fill the pool

$\frac{1}{33}$ = work rate of inlet pipe

$\frac{1}{34}$ = work rate of drain pipe

Using the formulae

Volume of flow=work rate $\times$ time

Let us assume complete time of pool to fill = 1

Remaining fraction of pool to be filled = $1-\frac{1}{3}=\frac{2}{3}$

$\begin{array}{l}{\frac{1}{33} x-\frac{1}{34} x=\frac{2}{3}} \\\\ {\frac{x}{33}-\frac{x}{34}=\frac{2}{3}}\end{array}$

$\frac{34 x-33 x}{33 \times 34}=\frac{2}{3}$

$34 x-33 x=\frac{2 \times 34 \times 33}{3}$

$\begin{array}{l}{x=\frac{2244}{3}} \\\\ {x=\frac{3168}{3}} \\\\ {x=748}\end{array}$

Time it will take to fill the pool = 748 hrs
