Answer:

Step-by-step explanation:
we know that
The surface area of a square prism is given by the formula

where
b is the length side of the square base
h is the height of the prism
we have

substitute

solve for h

Answer:
length of wire required to
fence is 175.84 cm
4 times
Step-by-step explanation:
P=2rπ
r=56cm/2
r=28cm
P=2*28*3.14
P=175.84cm
704m/175.84 cm= 4
Given the population mean is
and population standard deviation is
.
Now sample mean is
and standard deviation of the sample mean is

Use Z-score for finding the probabilities. Use a standard normal distribution table.
a)The probability

b)The probability

c)The probability

Answer:
- ∠BCA = 30°
- ∠FHC = 125°
- ∠A = 45°
- ∠GBC = 75°
- arc EBC = 260°
Step-by-step explanation:
Angle BCA intercepts arc FB, so is half its measure: 60°/2 = 30°.
Angle FHC is half the sum of the angles intercepted by its chords: (60°+150°+40°)/2 = 125°.
Angle A is half the difference of the arcs it intersects: (150° -60°)/2 = 45°.
Angle GBC is half the measure of the arc it intercepts: 150°/2 = 75°.
arc EBC is the sum of arcs EF, FB, and BC: 50° +60° +150° = 260°.
