Answer:
30×pi ft
Step-by-step explanation:
ST is the diameter.
the formula for the circumference of a circle is
C = 2×pi×r
r = radius = diameter / 2
so,
C = 2×pi×30/2 = pi×30
therefore, the first answer option is correct.
Area of circle = pi r squared = 113.1
so r squared =113.1/3.14
r=6.00159 by doing square root
Circumference = 2 pi r
2 times 3.14 times 6.00159 = 37.7 ft answer D
Answer:
Step-by-step explanation:
we know that
where
s is the side length, in units, of a cube
V is the volume of a cube in cubic units
For a
substitute in the formula
If Jason wants to build a cube with a minimum of 64 cubic centimeters
therefore
the minimum length side of the cube is 4 cm

Answer:
B. 24
Step-by-step explanation:
y and x have a proportional relationship, and y = 24 when x = 16
then
y÷x = 24÷16 = 1.5
Since y=36 then
36÷x = 1.5
then
x = 36÷1.5 = 24.
