We can find the volume of the cylinder using the next equation:
Where h represents the height and r represents the radius.
The radius is the half value of the cylinder. Then :
r=d/2
r=7yd
r=3.5yd
Replacing:
Hence, the volume is 98π yd³
98π yd³=307.9
The answer is decimal form is 307.9 ( The value is rounded to the nearest tenth).
Answer:
A) x = .9y
B) x + .9y = .038
Substituting A) into B)
.9y + .9y = .038
1.8y = .038
y = .038 / 1.8
y = 0.0211111111
From equation A)
x = .038 -.9*.02111111111111111111111
x = .038 -.019
x = .019
CHECK
x * .9 = .019
.019 + .9 * .021111111111111 = .019 + .019 = .038

Answer:
∠ XWZ is a right angle.
Step-by-step explanation:
See the given diagram.
In triangle WXZ, WY is an altitude.
So, ∠ WYZ = ∠ XYW = 90°
Now, given that ∠ ZWY = ∠ WXY.
Now, from Δ XYW, since, ∠ XYW = 90° so, ∠ WXY + ∠ YWX = 90° ....... (1)
⇒ ∠ ZWY + ∠ YWX = 90° {Since, ∠ ZWY = ∠ WXY}
⇒ ∠ XWZ = 90°
Therefore, the angle XWZ is right angle. (Answer)
