The area of a circular sun spot is growing at a rate of 1,200 km2/s.

Tpy6a [65]

A)

$\bf \textit{area of a circle}\\\\
A=\pi r^2
\\\\\\
\cfrac{dA}{dt}=\pi \cdot 2r\cfrac{dr}{dt}\implies \cfrac{dA}{dt}=2\pi r\cfrac{dr}{dt}\implies \cfrac{\frac{dA}{dt}}{2\pi r}=\cfrac{dr}{dt}\\\\
-----------------------------\\\\
\left. \cfrac{dr}{dt} \right|_{r=3000}\implies \cfrac{1200}{2\pi \cdot 3000}=\cfrac{dr}{dt}\\\\$

B)

$\bf A=\pi r^2\qquad A=490000\implies 490000=\pi r^2\implies \sqrt{\cfrac{490000}{\pi }}=r
\\\\\\
\left. \cfrac{dr}{dt} \right|_{r=\sqrt{\frac{490000}{\pi }}}\implies \cfrac{1200}{2\pi \cdot \sqrt{\frac{490000}{\pi }}}=\cfrac{dr}{dt}

Rosa can run 4 miles in 56 minutes.How many miles does rosa run if she runs 42 minutes?

Alex Ar [27]

Rosa runs 3 miles in 42 minutes.

I divided 42 by 56 to get the percentage that will be multiplied to 4 miles to get the number of miles Rosa runs in 42 minutes.

42 / 56 = 0.75 * 100% = 75%

75% * 4 miles = 3 miles.

3 miles within 42 minutes

The area of a square quilt is 289 square inches. There is a smaller square patch on the quilt with an area of 121 square inches.

alisha [4.7K]

Area of a square quilt = 289 square inches
Area of a smaller square quilt = 121 square inches

Area of a square = a²

Side length of big square quilt = √289 in² = 17 inches
side length of small square quilt = √121 in² = 11 inches

Perimeter of big square = 17 inches * 4 = 68 inches
perimeter of small square = 11 inches * 4 = 44 inches

difference = 68 inches - 44 inches = 24 inches.

Find the exact circumference of a circle with the given radius. 5 inches C = 2.5π in. 10π in. 25π in.

docker41 [41]

The circumference, C, of a given circle may be calculated through the equation,

C = 2πr

where r is the radius.

Substituting the known values from the given in this item,
C = 2(π)(5 in)
<em>C = 10π in</em>

Thus, the answer is this item is the second choice.
