Answer: 9 meters
Step-by-step explanation:
Hi, to answer this question we have to apply the formula:
Surface area if a cylinder (S)= 2 π r2 + 2 π r h
Where r is the radius and h is the height
Diameter is equal to 2r , so in our case:
14 =2r
r = 14/2 = 7 meters
Replacing with the values given and solving for h:
224 pi = 2 π 7^2 + 2 π 7 h
224 π - 2 π 7^2 / 2 π 7= h
703.71 -307.87 /43.98 = h
9 = h

Answer:
A). PR = 16.13 ft
B). QR = 9.64 ft
Step-by-step explanation:
Part (A).
From the figure attached,
ΔPQR is a right triangle,
m(PQ) = 14 ft
m(QR) = 8 ft
By applying Pythagoras theorem,
Hypotenuse² = (Leg 1)² + (Leg 2)²
(PR)² = (PQ)² + (QR)²
(PR)² = (14)² + (8)²
PR = √260
= 16.125
≈ 16.13 ft
Part (B).
If PR = 17 feet
and PQ = 14 feet
By applying Pythagoras theorem in ΔPQR,
PR² = PQ² + QR²
(17)² = (14)² + (QR)²
(QR)² = 289 - 196
QR = √93
= 9.644
≈ 9.64 ft
