Answer:

200.96 in2

Step-by-step explanation:

Area of a circle = nr²

n = 3.14

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

diameter = 2r

radius = 16 inches / 2 = 8 in

Area = 3.14 x 8² =  200.96 in²

Transformation involves changing the position of a shape.

The transformation from \triangle ABC to \triangle A'B'C' is 90 degrees clockwise rotation

Using the coordinates of A and A', we have:

A= (-6,3)

A'= (3,6)

Notice that the x-coordinate is <em>negated </em>and then <em>swapped </em>with the y-coordinate.

i.e.

(x,y) \to (y,-x)

The transformation of a point from <em>(x,y) to (y,-x)</em> is a 90 degrees clockwise rotation.

Hence, the transformation from \triangle ABC to \triangle A'B'C' is 90 degrees clockwise rotation

If the divisor is 4 and the quotient is 8, what is the dividend ?
kolbaska11 [484]
<h3>If the divisor is 4 and the quotient is 8, Then, dividend is 32</h3>

<em><u>Solution:</u></em>

Given that,

Divisor = 4

Quotient = 8

To find: dividend

We know that,

Dividend \div divisor = quotient

Therefore,

Dividend \div 4 = 8\\\\Dividend \times \frac{1}{4} = 8\\\\Dividend = 8 \times 4\\\\Dividend = 32

Thus, dividend is 32

Sand falls onto a conical pile at the rate of 10 cubic feet per minute. The radius of the pile is always equal to one half it al
Andreas93 [3]

Answer:

Either one of these.

Step-by-step explanation:

volumepile=1/3 (PI r^2)h

but r=h/2, so

volume=1/12 PI h^3

dv/dt=10 ft^3/min

but dv/dt=1/12 PI 3h^2 dh/dt

solve for dh/dt

This assumes you mean by "altitude" the height. If you mean altitude as slant height, you have to adjust the fromula

_______________________________________________

given: r = h/2

V = (1/3)π r^2 h

= (1/3)π (h/2)^2 (h)

= (1/12) π h^3

dV/dt = (1/4)π h^2 dh/dt

for the given data ...

10 = (1/4)π(25)dh/dt

dh/dt = 10(4)/((25π) = 1.6/π feet/min
