Answer:

x=291/76

Step-by-step explanation:

Convert:

1/2x(6x+ 1/2)=-0.8x+16-1.2

Remove parenthesis and move terms:

3x+1/4=-0.8x+14.8

Collect the like terms and convert:

3x+0.8x=14.8-1/4

Subtract the fractions:

3.8x=74/5-1/4

Divide both sides by 3.8:

3.8x=291/20

x=291/76

Diameter=16in

Radius= 16/2= 8in

Area= πr^2

Area= 3.132*8^2

Area= 201.09 in^2

pizzeria2

Diameter=15in

Radius= 15/2= 7.5in

Area= πr^2

The shown bellow question answer

Serhud [2]

Answer:

The area of the shape can be divided into the area of the rectangle, and the area of the semi-circle.

The area of the rectangle can be found by $11*4=44$

The area of a semi-circle can be found with the formula $\frac{1}{2} \pi r^2$ where r is the radius.

Since we know the diameter of the semi-circle is 4,

the radius will be 4 ÷ 2 = 2.

Therefore, the area of the semi-circle is $\frac{1}{2}\pi 2^2=\frac{1}{2}\pi*4=2\pi$

Therefore, the area of the shape is $44+2\pi$ or $50.283cm^2$ (3 decimal places)
