What is the surface area of a sphere with the given dimension? Express your answer to nearest hundredth. Use 3.14 for pi. Radius

pav-90 [236]

Okay. The equation for a sphere's surface area is A = 4 * pi * r^2. Let's plug 5 in for r.
$4 \pi (5^2) = 4(3.14)*25 = 100 * 3.14 = 314$
I got 314 cm^2 is the surface area, but it always helps to double check work! Hope this helps!

Franco read 3/8 of a chapter of his history book in 1/5 of an hour. At this rate, how many chapters of his history book can he r

Irina18 [472]

He can read $1\frac{7}{8}$ chapters of his history book in 1 hour.

Explanation

Franco read 3/8 of a chapter of his history book in 1/5 of an hour.

Suppose, he can read $x$ chapters of his book in 1 hour at this rate.

So, the equation according to the ratio of 'the chapter to the time' will be....

$\frac{x}{1}= \frac{\frac{3}{8}}{\frac{1}{5}}\\ \\ \frac{x}{1}=\frac{3}{8}*\frac{5}{1}\\ \\ \frac{x}{1}=\frac{15}{8} \\ \\ x= \frac{15}{8}= 1\frac{7}{8}$

So, he can read $1\frac{7}{8}$ chapters of his history book in 1 hour.

Basile [38]

So we can write

12% of x = 36

12/100 x = 36

x = 36 x 100/ 12

x= 300

So, 300 cookies were ordered in total.
