Answer:
Best approximation for the circumference of the plate = 18.84 inches
Step-by-step explanation:
Given in the question,
radius of a plate = 3 inches
π = 3.14
To find,
circumference of the plate.
As we know that formula to calculate circumference of a circle given radius
<h2>
2 π r</h2>
2 (π) (3)
2 (3.14) (3)
18.84 inches
So the circumference or perimeter of area = 18.84 inches

Answer:
Option 4
Step-by-step explanation:
4% = 0.04
2/5 = 0.4
3/8 = 0.375
So, the answer is 4%, 0.042, 3/8, 2/5.
The volume of a sphere is calculated like so:
v = 4*pi*r^3/3
so half sphere will have half that volume:
v = (<span>4*pi*r^3/3)(1/2)
</span>v = <span>4*pi*r^3/6
</span>plug in the data:
v = <span>4*pi*(10)^3/6
</span>v = 2094.4
that is the volume of the half sphere
Happy birthday, and the answer would be 3m(squared). The formula is LxH/2.
Step-by-step explanation:
the circumference of a circle is
C = 2×pi×r
with r being the radius.
the square side length is 22 cm. so, the circumference or perimeter of the square (and therefore the length of the wire) is
4×22 = 88 cm.
now, it is the same wire of the same length that is now forming a circle.
so, the circumference of the square is also the circumference of the circle.
therefore,
88 = 2×pi×r
44 = pi×r
r = 44/pi = 14.00563499... cm
so, rounded, radius = 14 cm.
