Answer:

Step-by-step explanation:

This is an example of "the square of a binomial."  There is a formula for such cases;

(a + b)^2 = a^2 + 2ab + b^2 (worth memorizing)

Thus, our (x + y)^2 = x^2 + 2xy + y^2

Calculate volume of hemisphere with radius 3.2 cm
Olin [163]

Answer:

V ≈ 68.63 cm³

Step-by-step explanation:

the volume (V) of a sphere is calculated as

V = \frac{4}{3}πr³

the volume of a hemisphere is half the volume of a sphere, so

V = \frac{1}{2} × \frac{4}{3} πr³ = \frac{2}{3} πr³ , then

V = \frac{2}{3} π × 3.2³

  = \frac{2}{3} π × 32.768

  ≈ 68.63 cm³ ( to 2 dec. places )
