Step-by-step explanation:

Area of square:

=a²

=12²

=144

Area of two quarter circles:

=2(¼×π×r²)

=2(¼×π×6²)

=2×28.72

=56.55

Finding the percentage:

=(56. 55÷144)×100

=0.3937×100

=39.27

subtract 100% by 39.27% to find the percentage of how much is shaded

=100-39.27

=60.73

=61 (rounded off to the nearest whole percent)

Organisers for a charity event sold 500 tickets. Adult price £3 and children £2. Money received from adult ticket sales is £400

Tatiana [17]

Answer: 280

Step-by-step explanation:

Quantity X Cost = Money Received

Adult: x 3 3x

Children: 500-x 2 2(500 - x) = 1000 - 2x

Adult = Children + 400

3x = 1000 - 2x + 400

3x = 1400 - 2x

5x = 1400

x = 280

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
r=1.5\\
h=18
