Answer:
The circumference of the circle is 52π
Step-by-step explanation:
To solve this exercise we first have to calculate the radius of the circle, for this we will use the formula of area of a circle and we will clear the radius
a = area = 676π
r = radius
a = π * r²
we clear r
r = √(a/π)
now we replace the known values
r = √(676π/π)
r = √(676)
r = 26
now we use the formula to calculate the circumference of a circle
c = π * 2r
c = π * 2 * 26
c = 52π
The circumference of the circle is 52π
Answer:
That is a lot of questions to answer. But I will try.
5)
a) 6 square units
b) 5/6
Second picture
1. Area = 6
2. Area = 4.5
3. Area = 20
4. Area = 9
5. Area = 17.5
Third picture
a) 8 units because if you move the bottom triangle to the top of the other triangle it makes a rectangle with height of 2 and length of 4.
I'm sorry I have to go I would love to finish this but I hope what I gave helps you!
Answer:
486
Step-by-step explanation:
if you mean 485.782 with a decimal then it would be 486
For every side you just add 90 to your equation. so #4 would be 360-125-125-55=(55)
