When a circular plate is heated in an oven, its radius increases at the rate of 0.01 cm/min. At what rate is the plate’s area in

m_a_m_a [10]

Answer:

3.14 cm²/min

Step-by-step explanation:

rate of increasing of radius, dr/dt = 0.01 cm/min

r = 50 cm

Area of plate, A = πr²

rate of increase of area

dA/dt = 2πr dr/dt

dA/dt = 2 x 3.14 x 50 x 0.01

dA/dt = 3.14 cm²/min

Thus, the increase of rate of area is 3.14 cm²/min.

Which equation correctly shows how to determine the distance between the points (9,-2) and (6.3) on a coordinate grid?

Nastasia [14]

Answer:

d = $\sqrt{(6 - 9)^{2}+ (3 - (-2))^{2} }$

Step-by-step explanation:

The distance formula is d= $\sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2} }$ .

6 is $x_{2}$ , 9 is $x_{1}$ , 3 is y $_{2}$ , and -2 is y $_{1}$ .

When you plug these into the formula, you get d = $\sqrt{(6 - 9)^{2}+ (3 - (-2))^{2} }$
