Circumference: 18.84 m
Area: 28.26
Explanation
For circumference, use the formula *d, where d=the diameter(the radius times 2).
For area, use the formula , where r=the radius. Make sure to square the radius first before multiplying by pi!
A good way to remember these formulas is Cherry(circumference) Pi() is Delicious(diameter) and Apple(area)
("are too")
Answer:
First know this,
The volume V of a cylindrical barrel is given by the formula. V = πr2h, where r is the barrel's radius and h is the barrel's height.
Rewrite the equation as πr2h=V π r 2 h = V . Divide each term by πr2 π r 2 and simplify. Divide each term in πr2h=V π r 2 h = V by πr2 π r 2 .

Answer:
Step-by-step Explanation:
==>Given:
radius (r) = 10 m
m<VCW = 97°
==>Required:
Length of arc VW
==>Solution:
Formula for length VW is given as 2πr(θ/360)
Using the formula, Arc length = 2πr(θ/360), find the arc length VW in the given circle
Where,
θ = 97°
r = radius of the circle = 10 m
Thus,
Arc length VW = 2*π*10(97/360)
Arc length VW = 20π(97/360)
Arc length VW = π(97/18)
Arc length VW = 97π/18 m
Our answer is,
