The exact circumference of a circle is 25π millimeters. What is the approximate area of the circle? Use 3.14 for π. Round to the nearest hundredth if necessary.
Answer: A = 490.63 mm^2
Step-by-step explanation: Hello! To find the area of a circle, you have to find the radius of the circle from the circumference given. The formula is Circumference/2(3.14) = Radius. To find the circumference, multiply 25 x pi, or 25 x 3.14. 25 x 3.14 is 78.5. Put 78.5 in the equation for the circumference. 78.5/2(3.14) = Radius
Simplify:
78.5/6.28 = 12.5
The radius is approximately 12.5.
The formula for the area of a circle is 3.14 x r^2 = A
Put 12.5 in for r or radius
3.14 x 12.5^2 = A, 12.5^2 = 156.25
3.14 x 156.25 = A
3.14 x 156.25 = 490.625
Rounded to the nearest hundredth is A = 490.63
Answer: hope this helps ♡
The approximate area of the circle is 49.736 mm²
Step-by-step explanation:
Area of circle = π × r²
To find the radius:
25 ÷ 3.14 = 7.96178343949 (← diameter d = 2r)
7.96178343949 ÷ 2 = 3.98089171974 (radius)
π × r² =
3.14 × 3.98089171974² =
3.14 × 15.8474988843 =
49.7611464967 ≈ 49.736

Answer:
Step-by-step explanation:
Yellow block closest side and farthest side: 2x1=2 2x2=4
Yellow block right and left side: 1x1=1 1x2=2
Yellow block bottom: 2x1=2
Yellow block top: 2x1=2
Purple block closest side and farthest side: 5x2=10 10x2=20
Purple block right and left side: 2x3=6 6x2=12
Purple block bottom: 5x3=15
Purple block top: 5x3=15 15-2=13
2+2+2+1+1+13+10+10+6+6+15= 68
The overlap effects the calculation of the surface area because the bottom of the yellow block and a part of the purple block overlaps making it so that you would count it two times instead of the area that is visible.
I like to think of it as spray painting the blocks and seeing where the paint sprays.

A gardener spread 2/3 of a bag of mulch evenly over his 6 equal-sized vegetable beds. How much mulch did he put on each vegetable bed?
Write your answer as a fraction or as a whole or mixed number.
Answer: 1/9
Step-by-step explanation: We can start the problem by using the concept of unit rate.
We know that the gardener spread 2/3 of a bag of mulch over his 6 vegetable beds. To find the amount of mulch per bed, we can divide the total amount of mulch by the number of beds.
So, the unit rate of mulch per bed is (2/3) / 6 = 1/9 of a bag of mulch.
So, the gardener put 1/9 of a bag of mulch on each vegetable bed.
Answer: 1/9
Step-by-step explanation:
If it was one bag, it would have been 1÷6 and the answer would have been 1/6 for each vegetable bed.
So if we do the same with 2/3, this is (2/3)/6. Let’s try this:
=[tex]\frac{2}{3}[/tex]÷[tex]\frac{6}{1}[/tex]
=[tex]\frac{2}{3}[/tex]×[tex]\frac{1}{6}[/tex]
=[tex]\frac{2}{19}[/tex]
=[tex]\frac{1}{9}[/tex]
Therefore, the gardener put 1/9th of the bag of mulch on each vegetable bed.

Your sister’s soccer team drinks 15 liters of water during their tournament. Water coolers are sold in gallon sizes. What is the smallest gallon water cooler they will need to buy? (1 gallon 3.8 liters)
Answer: 4 gallons
Step-by-step explanation:
I am pretty sure it is 4 gallons because if you multiply 3.8(2)=7.6 and then 3.8(3)=11.4 and finally 3.8(4)=15.2
So that is why I think that the smallest gallon water cooler they will need too by is a 4-gallon cooler.
