Find the area of semi circle , π = 3, d = 12
Answers
Answer:
120cm *squared*
Step-by-step explanation:
A = π r² to find a circle
half of diameter is radius so 12/2 = 6
3 x 6 (squared) = 108
we found the half circle then add 12
so we make a semi circle
108 + 12= 120
answer 120 cm *squared*

4. A rectangular field measures, 616m by 456m. Fencing
placed along its sides at equal distances. What
will be the distance between the posts if they are placedos
for apart as possible? How many posts are required?
Answers
Answer:
The number of posts required to fence the field are;
136 posts
Step-by-step explanation:
The measure of the rectangular field is given as follows;
The length of the rectangular field = 616 m
The width of the rectangular field = 456 m
Let 'x' represent the 'furthest distance possible between the posts
There will be one post at each of the four corners of the field
Let 'c' represent the number of posts at the four corners of the field
Therefore, the number of posts at the corner of the field, c = 4
Therefore, 'x' is highest common factor of 616 and 456
The prime factorization of 616 = 2³ × 7¹ × 11¹
The prime factorization of 456 = 2³ × 9 × 19
Therefore, the highest common factor of 616 and 456 = 2³ = 8
The distance between posts = 8 m
Let 'w' represent the number of posts on the 456 m side of the field less the posts at the corner corner of the field and let 'l' represent the number of posts on the 616 m side of the field less the posts at the corner corner of the field, we have;
The number of posts on the 456 m side less the corner post, w = 456/8 - 1 = 57 - 1 = 56
The number of posts on the 616 m side less the corner post, l = 616/8 - 1 = 77 - 1 = 76
The total number of posts required to fence the field, T = w + l + c
∴ T = 56 + 76 + 4 = 136
The total number of posts required to fence the field, T = 136 posts

Anthropologists approximate the height of a primate by the size of its humerus (the bone from the elbow to the shoulder) using the equation
H = 1.2L + 27.8,
where L is the length of the humerus and H is the height, in inches, of the primate.
An anthropologist estimates the height of a primate to be 60 in. What is the approximate length of the humerus of this primate? Round to the nearest tenth of an inch.
in
Answers
Answer:
26.83
Step-by-step explanation:
H=1.2L + 27.8
60=1.2x+27.8
minus 27.8 from both sides
32.2=1.2x
divide both sides by 1.2
x=26.83
In AXYZ, X = 7.7 inches, y = 4.2 inches and z=7.3 inches. Find the measure of Y to
the nearest degree.
Answers
Answer:
32.38°
Step-by-step explanation:
In AXYZ, X = 7.7 inches, y = 4.2 inches and z=7.3 inches. Find the measure of Y to
the nearest degree.
We solve using Cosine rule
Y = arc cos( x² + z² - y²/2xz)
x = 7.7 inches
z = 7.3 inches
y = 4.2 inches
Y = arc cos( 7.7² + 7.3² - 4.2²/2 × 7.7 × 7.3)
Y = 32.38°

what is the exterior angle?
Answers
The value of x° is 22° and exterior angle is 25.
Step-by-step explanation:
l can prove like this,
Here,2x°+(103-x)°=(6x-7)°...Being exterior angle
or,2x°+103°-x°=6x°-7°
or,x°+103°=6x°-7°
or,103°+7°=6x°-7°
or,5x°=110°
or,x°=110°÷5=22°
Now,
x°=22°
(6x-7)°=(6×22-7)°=125°

Distribute by multiplying into the bracket
=12x + 6 + 2x - 2
Group like terms by adding and subtracting
= 14x + 4
Answer:
1) Multiply and expand the brackets:
12x + 6 + 2x - 2
2) Combine like terms (combine terms that have an x together, and those that don't together.)
14x + 4
If the question wanted you to simplify the expression, then 14x + 4 is your answer. However, to solve for x, you could equate the expression to 0, but I'm not too sure of this part.
14x + 4 = 0
14x = - 4
x = - 4/14
x = - 2/7
