Area of sector = 1/2 * r^2 * x where r = radius and x = angle in radians
86 = 1/2 * r^2 * pi/4
r^2 = 2 * 86 * 4 / pi = 219
r = sqrt 219
= 14.80
Step-by-step explanation:
x = how many games won last year
x - 1 = how many games won each year
Answer:
298-275 = 23 cm thus D) is the answer
Step-by-step explanation:
First Box:
length l = 9.5 cm
width w = 5 cm
height h = 7 cm
diagonal d = 12.8160056 cm
total surface area S_tot = 298 cm2
lateral surface area S_lat = 203 cm2
top surface area S_top = 47.5 cm²
bottom surface area S_bot = 47.5 cm²
volume V = 332.5 cm³
Second Box:
length l = 7.5 cm
width w = 5 cm
height h = 8 cm
diagonal d = 12.0519708 cm
total surface area S_tot = 275 cm²
lateral surface area S_lat = 200 cm²
top surface area S_top = 37.5 cm²
bottom surface area S_bot = 37.5 cm²
volume V = 300 cm³
Answer:
33 inches
Step-by-step explanation:
In a quadrilateral ABCD, AB ∥ DC and AD ∥ BC.
AC = 20 in, BD = 20 in, AB = 13 in.
We want to find the perimeter of ΔCOD if point O is the intersection of the diagonals.
Since AB ∥ DC and AD ∥ BC, the point O divides the diagonals into two equal parts.
|OD|=|BD|/2 = 20/2 =10inch
Similarly,
|OC|=|AC|/2 = 20/2 =10inch
Also,
AB=CD=13 inch
Therefore,
Perimeter of ΔCOD= |OD|+|OC|+|CD|
=10+10+13
=33 inches
