Leno4ka [110]

Radius of the pan = 16cm

Formula for area of circle:

$\boxed { \boxed { \text {Area of a circle =} \pi r^2}}$

Find the area of the pan:

$\text {Area of the pan =} \pi (16)^2 = 804.25 \ cm^2$

$\boxed { \boxed {\text {Answer : The butter must cover 804.25 cm}^2}}$

An object falls 18ft in 2 seconds. Knowing the distance varies directly with the square of the time of the fall how long does it

AVprozaik [17]

Answer:

t=4.19 seconds

Step-by-step explanation:

Distance varies directly with the square of the time of the fall

It means,

D=kt^2

18ft in 2 seconds

D=kt^2

18=k*2^2

18=4k

k=18/4

=9/2

k=9/2

D=kt^2

D=79feet

79=9/2t^2

t^2=79÷9/2

t^2=79×2/9

=158/9

t=√158/√9

t=12.57/3

t=4.19 seconds

Bas_tet [7]

Answer:

Answer is option d 

Step-by-step explanation:

$given \: expression \: is \: {(x - 3)}^{2} = 5 \\ {x}^{2} - 6x + 9 = 5 \\ subtracting \: 5 \: on \: both \: sides \: we \: get \\ {x}^{2} - 6x + 4 = 0 \\ on \: solving \: the \: quadratic \: equation \: by \\ \: completing \: square \: method \\ {x}^{2} - 6x = - 4 \\ adding \: {3}^{2} on \: both \: sides \: w e\: get \\ {x}^{2} - 6x + {3}^{2} = {3}^{2} - 4 \\ {(x - 3)}^{2} = 5 \\ x - 3 + = \sqrt{5} \\ x = \sqrt{5 } + 3$
