(1) Find the rate of the cube's edge length with respect to time at s=30:

(2) Find the rate of the cube's surface area with respect to time at s=30:

Therefore, the surface area increases when the length of an edge is 30 cm at a rate of
.
Step-by-step explanation:
area of the minor sector= angle of the sector/360 * πr²
= 77/360 *22/7* 10.7²
= 76.96in²
appx 77.0in²
I'm going to assume that you are asking how deep he jumped. He jumped from 4 feet high into a 1 foot deep hole, so, we need to add.
4 + 1 = 5
Therefore, Jose jumped a total of 5 feet.
Best of Luck!
Notice that 56° = 45° + 11°. Then
tan(56°) = sin(56°) / cos(56°)
… = sin(45° + 11°) / cos(45° + 11°)
… = (sin(45°) cos(11°) + cos(45°) sin(11°)) / (cos(45°) cos(11°) - sin(45°) sin(11°))
Recall that sin(45°) = cos(45°) = 1/√2, so we can cancel each term involving 45° :
tan(56°) = (cos(11°) + sin(11°)) / (cos(11°) - sin(11°))
