Hello!
To find the area, we use the formula A=pir², where pi=3.14 and r= the radius.
To solve, we find half of the diameter, which is the radius. Half of 53 is 26.5. We square this number and then multiply it by pi. 26.5·26.5=702.25. Now we multiply by pi. 702.25·3.14=2,205.065.
Our final answer is about 2,205.1 cm².
I hope this helps!
Answer: 6 feet
Step-by-step explanation:
Given that a 4-foot by 8-foot rectangular piece of plywood will be cut into 4 congruent rectangles with no wood left over and no wood lost due to the cuts
Let assume that the 4 rectangles will be of the same area since they are congruent.
The area of the big rectangle will be
Area = 4 × 8 = 32
Divide 32 by 4
32/4 = 8
Suggest the two possible numbers in which their product will be equal to 8
4 and 2 or 8 and 1
If 4 and 2
The perimeter = 2L + 2B
Substitute the 4 and 2 into the formula
Perimeter = 2(4) + 2(2)
Perimeter = 8 + 4
Perimeter = 12
If 8 and 1
Perimeter = 2(8) + 2(1)
Perimeter = 16 + 2 = 18
The positive difference, in feet, between the greatest possible perimeter of a single piece and the least possible perimeter of a single piece will be:
18 - 12 = 6 feet
Answer:
A) Each of the smaller donations is $20.
B) The larger donation is greater than the smaller donations by $15.
Step-by-step explanation:
4+4+7 is equal to 15, and divide 75 by 15 to get $5 per part. Multiply 4 by 5 to get $20 for a smaller donation, and 7 by 5 to get $35 for the larger donation. Hope this helped :)
