atroni [7]

Answer: 63.59cm²

Step-by-step explanation:

The area covered by the pitch will be gotten by finding the value of the area of the circle and this will be:

Area of q circle = πr²

where,

π = 3.14

r = radius = diameter/2 = 9cm/2 = 4.5cm

Area = πr² = 3.14 × 4.5²

= 3.14 × 20.25

= 63.59cm²

Therefore, the area covered by the pitch is 63.59cm²

Jeremiah bought three gallons of ice cream and four containers of strawberries for $19.50. Gary bought five gallons of ice cream

Gennadij [26K]

Answer:

Cost of $1$ gallon of ice cream $=\$3.5$

Cost of $1$ container of strawberries $=\$2.25$

Step-by-step explanation:

Let cost of $1$ gallon ice cream $=\$x$

Let cost of $1$ container of strawberries $=\$y$

<u>Jeremiah's purchase</u>

Jeremiah bought $3$ gallon of ice cream

so total spend on ice cream = cost of $1$ gallon $\times$ total gallons

$=x\times3\\=3x$

Jeremiah bought $4$ container of strawberries

So total spend on = strawberries =cost pf $1$ container $\times$ total container

$=y\times4\\=4y$

Jeremiah's total expenditure $=\$19.50$

$3x+4y=19.50 .......(1)$

<u>Gary's purchase</u>

Gary bought $5$ gallons of ice cream

so total spend on ice cream = $5\times x=5x$

Gary bough $2$ containers of strawberries

so total spend on strawberries = $2\times y=2y$

Gary's total expenditure $=\$22$

$5x+2y=22.....(2)$

solve eqn(1) and eqn(2)

$3x+4y=19.50\\5x+2y=22$

multiply eqn(2) by (2) and eqn(2)-eqn(3)

$(10x-3x)+(4y-4y)=(44-19.50)\\\\7x=24.5\\\\x=\frac{24.5}{7}\\\\x=3.5$

Substitute in eqn(2)

$5\times3.5+2y=22\\\\2y=22-5\times3.5=22-17.5\\\\2y=4.5\\\\y=\frac{4.5}{2}\\\\y=2.25$

Cost of $1$ gallon of ice cream $=\$3.5$

Cost of $1$ container of strawberries $=\$2.25$
