Given:
The radius of the sphere is 6 in.
To find:
The volume of the sphere.
Solution:
We know that, the volume of a sphere is
Where, r is the radius of the sphere.
Putting r=6, we get
The volume of the sphere is 904.78 inches cubed.
Therefore, the correct option is C.
Answer:
A. 754 cm²
Step-by-step explanation:
Amount of cardboard needed = surface area of the cone
Curved surface area of the cone = πrl
Where,
π = 3.14
r = ½(20) = 10 cm
l = 24 cm
Plug in the values into the formula
Curved surface area = 3.14 × 10 × 24 = 753.6 ≈ 754 cm²
The answer A. 7 + 4 because it’s equal to 11 and 4-(-7) is 11
Answer:
Step-by-step explanation:
Do you mean log(10^8x), or log(10^(8x))? The parentheses change the meaning.
log(10^8x) = log(10⁸x) = log(10⁸) + log(x) = 8 + log(x)
log(10^(8x)) = log(10⁸ˣ) = 8x
