General equation of line
y = mx+ c
slope = m
y-intercept = c
y= -2x + 70
slope = -2
intercept = 70
Answer:
1. 20ft²
2. 63m
Step-by-step explanation:
Terms to know before you start:
r: radius
d: diameter
1. Area of a circle: πr² or π × r × r
π: 3.14
Diameter: 5 feet
Radius: , = 2.5 feet
Area: 3.14 × 2.5 × 2.5
Area: 19.625 ft²
Area (to the nearest whole number): 20ft²
2. There are two ways in solving this question.
The first and faster method:
Circumference: πd or π × d
π: 3.14
d: 20m
Circumference: 3.14 × 20
Circumference: 62.8m
Circumference (to the nearest whole number): 63m
The second method:
Circumference: 2πr or 2 × π × r
π: 3.14
r: , = 10m
Circumference: 2 × 3.14 × 10
Circumference: 62.8
Circumference (to the nearest whole number): 63m
