Alisiya [41]

Answer:

1134.1 [cm²]

Step-by-step explanation:

A=πr2

Circle area = π * r² = π * 361 [cm²] ≈ 1134.1 [cm²]

π ≈ 3.14159265 ≈ 3.14

d = r * 2 = 19 [cm] * 2 = 38 [cm]

A cube has an edge of 2 feet. The edge is increasing at the rate of 3 feet per minute. Express the volume of the cube as a funct

Harrizon [31]

Answer:

36 ft³/min

Step-by-step explanation:

Given that:

Let assume that length of the cube = m

Then;

m = 2 feet &;

$\dfrac{dm}{dt}= 3 \ ft/ min$

The volume (V) = m³

By differentiating with respect to t, we get

$\dfrac{dV}{dt} = 3m^2 \dfrac{dm}{dt}$

$\dfrac{dV}{dt} = 3(2)^2 \times 3$

$\dfrac{dV}{dt} = 12 \times 3$

= 36 ft³/min
