Question 26)
Circumference = πD
To find the arc of a quadrant, divide the circumference by 4 = 1/4 πD
Diameter = Radius x 2 = 24 x 2 = 48
Circumference of the arc of the playground = 1/4 x π x 48 = 12π = 37.70 ft
Distance around the playground = arc + radius + radius
Distance around the playground = 37.7 + 24 + 24 = 85.70 ft (nearest hundredth)

Answer:
Step-by-step explanation:
Nine less than twice x : 2x - 9
Three more than x : x + 3
2x - 9 = x + 3
2x -x - 9 = 3
2x -x = 3 + 9
x = 12

Answer:
Radius, r = 2.80 cm
Step-by-step explanation:
Given the following data;
Volume of cylinder = 207 cm³
Height = 8.4 cm
Pie, π = 3.14
To find the radius of the water bottle;
Mathematically, the volume of a cylinder is given by the formula;
V = πr²h
Where;
V is the volume of a cylinder.
r represents the radius of the cylinder.
h represents the height of the cylinder.
Substituting into the formula, we have;
207 = 3.14 * r² * 8.4
207 = 26.376r²
r² = 207/26.376
r² = 7.85
r = √7.85
Radius, r = 2.80 cm
