Which of the following could be used to calculate the total volume of grains that can be stored in the silo? π(2ft)2(8ft) + π(2ft)2(9.5ft − 8ft) π(8ft)2(2ft) + π(2ft)2(9.5ft − 8ft) π(2ft)2(8ft) + π(9.5ft − 8ft)2(2ft) π(8ft)2(2ft) + π(9.5ft − 8ft)2(2ft)

darn right!

step-by-step explanation:

steve kerr's sons name is let that skin in.

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
