I'm gonna do number 8 but do the SAME steps for the rest.....take the denominator multiply it by the whole number then add that answer to the numerator so now it will be 23/5×15/4 ... once u have that just multiply across but DON'T CROSS MULTIPLY multiply straight across and u'll get ur answer... answer to 8 is 345/20 now divide that answer like this.. 345÷20= 17.25

Diameter = 4 cm
Radius = Diameter/2 = 2 cm
Area of circle :




Circumference of circle :



<h2>Therefore, </h2><h3>Diameter = 4 cm</h3><h3>Radius = 2 cm</h3><h3>Area = 12.56 cm²</h3><h3>Circumference = 12.56 cm</h3>
<h2><u>

</u></h2>
Circumference = 15 feet (given)
Radius :







Diameter = r×2 = 2.38 × 2 = 4.76 feet
Area :



<h2>Therefore, </h2><h3>Diameter = 4.76 feet</h3><h3>Radius = 2.38 feet</h3><h3>Area = 17.78 ft²</h3><h3>Circumference = 15 feet</h3>
<h2><u>

</u></h2>
Diameter = 2 cm (given)
Radius = D/2 = 2/2 = 1 cm
Circumference :



Area :



<h2>Therefore, </h2><h3>Diameter = 2 cm</h3><h3>Radius = 1 cm </h3><h3>Area = 3.14 ft²</h3><h3>Circumference = 6.28 feet</h3><h2 /><h2><u>

</u></h2>
Radius = 4.3 mm
Diameter = r×2 = 4.3 × 2 = 8.6 mm
Circumference :



Area :




<h2>Therefore, </h2><h3>Diameter = 8.6 mm</h3><h3>Radius = 4.3 mm</h3><h3>Area = 58.95 mm²</h3><h3>Circumference = 27 mm</h3>
Answer:
23 divide by 9 =2.55555555556
Step-by-step explanation:
I'm assuming you're trying to simplify the expression?
If so, start by combining like terms.
4x+56-57
becomes 4x-1
That is the furthest you can simplify. If it had an equals sign, it would be an equation, and you would solve for x algebraically. But, since there is no equals sign, it is just an expression, and you simplify it to the best of your ability.
Hope this helps!
