What is the volume of a ball that has the length 1.3 cm has the width of 1.3 cm and has the height of 1.3 cm?

Answers

I'm taking these lengths as the diameter of this ball.

A ball is in the shape of a sphere.

The formula for finding the volume of a sphere is: (4)/(3) \pi r^3

\r = 0.65

∴ Volume = (4)/(3)*(22)/(7) * 0.65*0.65

=   1.77 cm^2  (approx.)

Least to greatest

1/2 0.4. 30%

Answers

1/2=50/100=0.5
0.4=0.4
30%=30/100=0.3

0.5,0.4,0.3 order
0.3,0.4,0.5

aka
30%, 0.4, 1/2
I would change all these to decimals. 1/2 is 0.5, 0.4, and 30% is 0.3
Therefore, least to greatest, it is 30%, 0.4, and 1/2. Good luck!

Lines g and h are parallel and m 1 = 65°. What is m 8?



A.
25°

B.
65°

C.
115°

D.
155°

Answers

Answer:

Option B 65\°

Step-by-step explanation:

we know that

If the lines g and h are parallel

then

m<8=m<1 -----> by alternate exterior angles

we have that

m<1=65\°

therefore

m<8=65\°
m 1 = m 4 (v.o.a.)
since g parallel to h
m 4 = m 8
m 8 = m 1 = 65°
