tanB=tanY
cosB=cosY
sinB=sinY

$\\ \rm\hookrightarrow sinY=\dfrac{P}{H}=\dfrac{9.6}{29.6}=0.32$

$\\ \rm\hookrightarrow cosY=\dfrac{B}{H}=\dfrac{28}{29.6}=0.94$

$\\ \rm\hookrightarrow tanY=sinY/cosY=0.34$

A cookie recipes call for 2 3/4 cups of flour and 2 1/2 cups of sugar. Will you be using more flour or sugar to bake the cookies

Ghella [55]

More flour cause you put the fractions over the same denominator and change to an improper fraction to get 2 3/4 = 11/4 and 2 1/2 = 5/2 = 10/4 and 11/4 is greater than 10/4.

Luba_88 [7]

Answer:

The volume of a sphere:

$V \approx 3053.628$ $cm ^3$

or

$V \approx 3053.63$ $cm^3$ (Rounded to the nearest hundredth if needed)

Step-by-step explanation:

-To find the volume of sphere, you need this formula to help you solve the problem:

$V = \frac{4}{3} \pi r^3$

-Use the given radius $9$ for the formula:

$V = \frac{4}{3} \pi 9^3$

-Then, you solve:

$V = \frac{4}{3}\pi \times 9^3$

$V = \frac{4}{3} \pi \times 729$

$V = \frac{4 \times 729}{3} \pi$

$V = \frac{2916}{3} \pi$

$V = 972\pi \approx 3053.628$ $cm^3$

-Round up to the nearest hundredth if needed:

$V = 3053.63$ $cm^3$
