Answer:

8 π .

Step-by-step explanation:

radius increases at a constant rate of 1 in/sec.

dr / dt = 1

where r is radius .

radius after 4 sec

r = 1 x 4 = 4 in

area A = π r²

differentiating both sides

dA / dt = 2 π r dr / dt

Putting dr / dt  = 1 , r = 4 in

dA / dt = 2 π x 4 x 1

= 8 π sq in per sec.

Area increases at the rate of 8 π per sec.

MARKING BRAINIEST!!! PLEASE HELP ASAP!!!
borishaifa [10]

Answer: B, 64

Step-by-step explanation:

To simplify this, first simplify all the parenthesis and multiply.

When an entire expression is raised to another exponent, everything in the parentheses is raised to that degree.

As such:

(2w^{-2}})^3 = 8 * w^{-6

You can then multiply this and the other expression:

8w^{-6} * 8w^6 = 8 * 8 * w^6 * w^{-6} = 64 * w^0

As such, the correct choice is B. The 'w's cancel each other out.

1/3 x 3 = 0.9

15 + 0.9 = 15.9

Hope this helps! :)

What is the area of cross-section ADGF of this right rectangular prism?
dedylja [7]

Answer:

C.52 square units

Step-by-step explanation:

We are given that

Length of cross-section ADGF,l=13units

Length of cross-section ADGF, b=4 units

We have to find the area  of cross-section ADGF of this right rectangular prism.

We know that

Area of rectangle=l\times b

Using the formula

Area of cross-section ADGF of this right rectangular prism

=13\times 4

Area of cross-section ADGF of this right rectangular prism=52square units

Option C is correct.

C.52 square units
