I believe yo meant c=2pir but ok
c=2r
divide both sides by 2
c/2=r
if you forgot tthe pi
c=2pir
divide by 2pi
c/(2pi)=r
The answer would be -x^2 + 6x - 3/2
Answer:
Isolate.
Step-by-step explanation:
To solve a one-step equation, you must isolate the variable.
For example,
3x = 9.
You must isolate x, which just means you have to get x by itself.
Divide by 3 on both sides to get x by itself.
x = 3.
The answer to this question is isolate.
Answer:
X = 6
Step-by-step explanation:
4x - 2 = 3x + 4 /subtract -3x
x - 2 = 4 /add 2
x = 6
Answer:
a. 113.1 cm^3.
b. 339.29 cm^3.
c. 18 cm.
d. 508.94 cm^3.
e. 169.65 cm^3.
Step-by-step explanation:
a. (4/3) * pi * (3^3) = (4/3) * pi * 27 = 36 * pi = 113.0973355, which is about 113.1
.
b. 113.0973355 * 3 = 339.2920066, which is about 339.29 cm^3.
c. Since the radius of a tennis ball is 3 cm, the diameter is 6 cm. There are three tennis balls, and the diameters added up become the height of the cylinder. 6 + 6 + 6 = 18 cm.
d. pi * (3^2) * 18 = pi * 9 * 18 = pi * 162 = 508.9380099, which is about 508.94 cm^3.
e. 508.9380099 - 339.2920066 = 169.6460033, which is about 169.65 cm^3.
Hope this helps!!
