Answer:
1. 8820.26 yds^2
2. 101.265 m^2
Step-by-step explanation:
For both problems you need to use the equation π*r^2 which is the area of a circle and where r is the radius of the circle. The radius is also equal to 1/2 the diameter so using this we can figure out the are of the first circle
For the second problem we have to find the area of the circle with and without the sidewalk around it and subtract them from each other
Answer:
translation
Step-by-step explanation:
because it's only being moved left by one unit
Answer:
Addition property of equality
Step-by-step explanation:
The given expression is :
We need to find the first step to solve this expression.
For this, we add 3/4 to both sides of the equation i.e.
So, we have used the addition property of equality.
The sign for less than is <.
The parts of the sum are 55 and 80.
Step-by-step explanation:
Let,
'x' be the smaller part and
'y' be the greater part of the number.
The sum is x+y = 135. --------(1)
The greater part y = x+25. ---------(2)
Substitute (2) in (1),
⇒ x+(x+25) = 135
⇒ 2x+25 = 135
⇒ 2x = 110
⇒ x= 110/2
x = 55
The smaller part is 55.
Substitute x=55 in (2)
y = 55+25 = 80
The greater part is 80.
