Answer:
B
Step-by-step explanation:
The circumference of a circle can be described as the linear distance round the circle
The circumference of a circle = 2πr or πD
π = 3.14
r = radius
d = diameter
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
π = circumference / 2r or circumference / D
37.68 / 12
Answer:
120 ft²
Step-by-step explanation:
The formula to find the area of a triangle is :
Area =
× base × height
Given that,
base ⇒ 30 ft
height ⇒ 8 ft
<u>Let us solve it now.</u>
Area =
× base × height
Area =
× 30 ft × 8 ft
Area =
× 240 ft²
Area =<u> 120 ft²</u>
Answer:
c
Step-by-step explanation:
To find the optimized value you need to find where the vertex(tip) of the parabola
use

to find the optimized x value
y= -w^2 +100w + 0

x = 50
answer: 50
