Answer:
3.5
Step-by-step explanation:
you want to add all of the balls together and then divide by 4 because that's how many color balls there are
Step-by-step explanation:
tan 60 = 21 ÷ y
1.73 = 21 ÷ y
y = 21 ÷ 1.73
y = 12.14
tan 30 = x÷ 12
0.6 x 12 = x
x = 7.2
<u>Given</u>:
Given that the radius of the sphere is 9 cm
We need to determine the volume of the sphere.
<u>Volume of the sphere:</u>
Let us determine the volume of the sphere.
The volume of the sphere can be determined using the formula,

where r is the radius of the sphere.
Substituting r = 9 in the above formula, we get;




Thus, the volume of the sphere is 972π cm³
Hence, Option B is the correct answer.
Answer:
A and C
Step-by-step explanation:
for A
QT/RT=ST/QT=QS/QR
There are two QT's in this
so
(QT)^2 = RT * ST
FOR B
there is no RT twice
for C
QR/RT RS/QR
There is a QR twice
so QR^2=RT*RS
FOR D there is no RT twice
