Answer:
5 cm
Step-by-step explanation:
The formula for the volume of a cylinder is
V = πr²h
Data:
V = 1726 cm³
h = 22 cm
Calculation:
1726 = 3.14 × r² × 22
1726 = 69.08r²
Divide each side by 69.08
24.99 = r²
Take the square root of each side
r = 4.999 cm ≈ 5 cm
The approximate radius of the cylinder is 5 cm.
Length=18
Width/Breadth =10
Height=2
The formula for a diagonal face of a cuboid is=√(l²+ b²)
Face diagonal=√(18²+10²)
= 20.59 to 2.d.p
The formula for the body diagonal of a cuboid is=√(l² + b² + h²)
Body diagonal=√(18² + 10² + 2²)
=20.69 to 2.d.p
1. multiply both sides by 2
<em>3b-4=2c</em>
2. add 4 to both sides
3b=2c+4
3. divide both sides by 3
b=
30 ft^2
Break the figure into smaller pieces:
5*2=10
10*2=20
Add the areas
20+10=30
The are of the figure is 30 ft^2
0.72, 3/4, 0.799, 4/5, 9/10
Let's start by converting all of these into decimal form to make this easier.
3/4=0.75, 4/5=0.8, and 9/10=0.9.
Now, it's clear that the correct order is:
0.72, 0.75, 0.799, 0.8, 0.9
Converting the fractions back, you get:
