Since there are 3 and assuming that they're the same size each radius is 1.5, as is the radius of the base of the cylinder. So you have to figure out the volume of one of the balls and multiply it by three. Formula: (4/3) * pi * radius^3. The volume of all three is 42.42. Then you need to find the volume of the cylinder. formula: pi * h * r^2. So it is 63.62. You now take this measure and subtract the volume of the three balls: 21.2in^3. To find the percentage, take 21.2/63.62. Then multiply by 100. The answer is 33.32, so your final answer is A.

If ‘p’ and ‘q’ are co-interior angles, write the relation between them

Alexandra [31]

Answer and Step-by-step explanation:

Co-Interior angles add up to 180 degrees.

That means the relation between angles p and q, which are co-interior angles, is that, when added together, they equal to 180 degrees.

solve systems of equation. equation number 1: 9 x squared + 4 y squared equals 144. equation 2: x squared plus y squared equals

grigory [225]

$9x^{2} + 4y^{2} =144$
$x^{2} + y^{2}=24$

$9x^{2} + 4y^{2} =144$
$4x^{2} + 4y^{2}=96$
by the difference
5 $x^{2}$ =48
so x= $\sqrt{\frac{48}{5}}$ or x=- $\sqrt{\frac{48}{5}}$
and $y^{2}$ =24- $\frac{48}{5}$
then y= $\sqrt{\frac{72}{5}}$ or - $\sqrt{\frac{48}{5}}$

What is the radius of a circle that has a circumference of 81.64 meters?

wlad13 [49]

R≈12.99
c = Circumference=pid= 81.64 To find the radius of a circle you can just divide the diameter by 2.
pi = 3.14 
d = diameter=c/3.14 Pi is always 3.14 or 22/7. 
d = 81.64/3.14 
d = 26 
r= radius= 26/2 
radius=13 cm

A rectangular piece of land measures 250 m by 220 m. Each side is to be fenced with 3 rows of wires. What is the length of the w

nexus9112 [7]

Answer:

2,820 m

Step-by-step explanation:

Given that the rectangular piece of land measures 250m by 220 m, the perimeter of the rectangle gives the length of wire required to fence it once.

The perimeter p of a rectangle of length l and width b is given as

p = 2(l + b)

Hence p = 2( 250 + 220)

= 2 * 470

= 940 m

Since each side is to be fenced with 3 rows of wires, the length of wire required

= 3 * 940m

= 2,820 m
