Formula- A = π r²
a= area
r= radius
diameter of the circle- 3.75 x 2 = 7.5
hope this helps :)
This is how I do it. If it is a negative minus a negative, I combine the two - signs to make it an addition problem. Ex. -3 - -4 makes -3+4. The answer would be one.
If it is a negative plus a negative, keep the sign on the greater number and take away the sign the smaller number. Ex. -7 + (-9). Keep the sign on the 9. -7 - 9. The answer would be -16.
Answer:
a=-3
Step-by-step explanation:
5a+a=-10-8
6a=-18
a=-18/6
a=-3
The 4 consecutive integers are 95, 96, 97 and 98.
The fourth integer is 98.
<u>Step-by-step explanation:</u>
Let us consider the 4 consecutive integers to be 'x' , 'x+1' , 'x + 2' , 'x + 3'
The sum of the 4 consecutive integers= 386
x + (x+1) + (x+2) + (x+3) = 386
4x + 6 = 386
4x = 380
x = 380/4
x = 95
x+1 = 96
x+2 = 97
x+3= 98
The 4 consecutive integers are 95, 96, 97 and 98.
The fourth integer is 98.
