Answer:
double the radius.
Step-by-step explanation:
Quadruple means 4 times. So you want to make the volume 4 times larger than it currently is.
This can be a little nasty because both numbers are the same.
V = 1/3 pi * r^2 * h
V = 1/3 3.14 * 4.8^2 * 4.8
V = 115.75296
Now if you double the radius, the volume becomes 4 times larger (or it should)
V= 1/3 * 3.14 * (9.6)^2 * 4.8
V = 463.012
Did that make the original volume larger?
115.75296 * 4 = 463.012 rounded.
Answer:
The circumference of the circle is about <u>166.42 </u>cm.
The area of the circle is about <u>2205.07 </u>cm².
Step-by-step explanation:
Diameter = 53 cm
Radius = r = 53cm/2 = 26.5 cm
π = 3.14
Circumference = C = 2 π r
C = 2(3.14)(26.5cm) = 166.42cm
The circumference of the circle is about 166.42cm.
Area = A = π r²
A = (3.14)(26.5cm)² = 2205.07 cm²
The area of the circle is about 2205.07 cm².
B)
1.80c +3h = 288.60
c=1 -2h
1) Gathering the data
Cold lunch (c) : $1.80
Hot lunch (h) : $3.00
Total $288.60
c = 1 -2h
2) Let's set up a system of equations, based on that
1.80c +3h = 288.60 <em>This equation relates the cost of those lunches</em>
c=1 -2h <em>The relationship between the number of lunches</em>
