Answer: x= 8\sqrt{3} over 3, x= 8 \sqrt{3} over 3
Step-by-step explanation:
Let's start with the area of a circle formula: A = pi * r^2, where r is the radius. The radius is half the diameter. Since the diameter here is 6, the radius is 3. Now we can start solving!
1) A = pi* (3^2)
2) A = 9pi
The area in terms of pi is 9pi cm^2.
I got 9pi cm^2, but it is always helpful to double check work. Hope this helps!
Answer:
5 pieces of 40 cm
Step-by-step explanation:
A Bar of steel is 340 cm long Issa cuts two 55cm lengths of the bar
He then cuts the rest into as many 40cm lengths as possible
Work out how many 40cm lengths of bar Issa cut.
so
340cm - 55 cm - 55 cm = 230 cm remains
<u>230 cm </u>to cut into 40 cm as many as possible
40 cm
therefore, there are 5 pieces of 40 cm
