SOLVE ONE AND TWO I WILL GIVE BRAINLIST

1. The radius is 90 ft.

2. 31.4 cm.

Step-by-step explanation:

1. The way to find the radius with just the diameter, is to divide by two.

2. When finding circumference, you need to multiply the diameter by 3.14 (pi), making it 10 x 3.14.

The radius is 90

Step-by-step explanation:

the line in the middle of the circle is the diameter so in order to find the radius you need to find half of the diameter. Half of the diameter (180) is 90 90 the radius is 90.

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3

x-3y=4
