The answer would be 240 because 12 times 8 equals 96 and 18 times 8 equals 144 but you have to add it so the answer is 240
taking 2 to the other side ⇒
= 5 x 2
3x=10
taking 3 to the other side ⇒ x =
x = 3.34
Answer:
A = 0.785m²
B = 31400cm²
C = 7850cm²
D = 785,000mm²
Step-by-step explanation:
To solve this question, we'll have to find the area of a circle which is
Area of a circle = πr²
1. The diameter of the circle = 1m
Area of a circle = πr²
r = radius of the circle
π = 3.14
Radius = diameter / 2
Radius = 1 / 2 = 0.5m
Area = 3.14 × (0.5)²
Area = 3.14 × 0.25
Area = 0.785m²
2. Radius = 100cm
Area of a circle = πr²
Area = 3.14 × (100)²
Area = 3.14 × 10000
Area = 31400cm²
3. Diameter = 100cm
Area = πr²
Radius = diameter / 2
Radius = 100 / 2
Radius = 50cm
Area = πr²
Area = 3.14 × (50)²
Area = 3.14 × 2500
Area = 7850cm²
4. Radius = 500mm
Area = πr²
Area = 3.14 × (500)²
Area = 3.14 × 250,000
Area = 785,000mm²
Hey there!
BOD is a 90 degrees angle. Make an equation for that angle. 15+12+x=90. Simplify this to 27+x=90. You need to isolate x, so subtract 27 on each side to get x=63. C is the answer.
I hope this helps!
Answer:
y = -1x + 5
Step-by-step explanation:
use the eqation y - y1 = m (x - x1)
plug in ur slope as m and you x and y points
y - 3 = -1 ( x -2 )
distribute the slope --> y - 3 = -1x + 2
add three to both sides --> y = -1x + 5
