Answer:
The product of these two numbers is 1239.
Step-by-step explanation:
Given that
a + b = 80
a - b = 38
Add both equation :
a + b = 80
a - b = 38
2a = 118
a = 59
Put value of a in any 1st equation
a + b = 80
b = 80 - 59
b = 21
<em>Product : </em>
a x b = 59 x 21
= 1239
we have the two numbers, x and y
x - y = 3
y = 0.75x
x - 0.75x = 3
0.25x = 3
x = 12
We substitute x into an equation: y = 0.75x
0.75 x 12 = 9 so y = 9
They have a difference of three
x = 12 and y = 9

Answer:
The area of each section of the circle is 25\pi\ m^{2}25π m2
Step-by-step explanation:
we know that
The area of a circle is equal to
A=\pi r^{2}A=πr2
we have
r=10\ mr=10 m
substitute
A=\pi (10^{2})=100\pi\ m^{2}A=π(102)=100π m2
To find the area of each section divide the complete area of the circle by 44
so
100\pi\ m^{2}/4=25\pi\ m^{2}100π m2/4=25π m2
