107 / 1000 = 0.107
Answer:
A = 64 pi
or approximately 200.96
Step-by-step explanation:
The diameter is twice the radius
d = 2r
16 = 2r
Divide by 2
16/2 = 2r/2
8 =r
The area of a circle is
A = pi *r^2
A = pi*(8)^2
= pi *64
Or if we approximate pi as 3.14
A = (3.14) * (64)
A = 200.96
Answer:
<h2>The polygon has 12 sides</h2>
Step-by-step explanation:
The sum of interior angles of a polygon is given by
<h3>( n - 2) × 180</h3>
where
n is the number of sides
From the question the sum is 1800°
Substitute the value into the above formula and solve for the number of sides
That's
( n - 2) × 180 = 1800
180n - 360 = 1800
180n = 1800 + 360
180n = 2160
Divide both sides by 180
n = 12
Therefore the polygon has 12 sides

Answer:
x =150 men
Step-by-step explanation:
Think of the total as workdays
125men* 120days = 15000 workdays
We still need 15000 workdays
100 days * x = 15000workdays
Divide by 100
x = 15000/ 100
x =150 men
Given:
12 sq.ft of paper @ $1/sq.ft
4 ft of wood @ $3/ft
14 yds of string @ $2/yd
Part A:
total cost for one kite
=12 sq.ft of paper @ $1/sq.ft
4 ft of wood @ $3/ft
14 yds of string @ $2/yd
= 12*$1 + 4*$3 + 14*$2
=$12 + $12 + $28
=$52
Part B:
Total cost for four kites
= 4* cost for one kite
= 4*$52
=$208
