Answer:
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as
Area = length × width
Length = 100 m
Width = 52 m
Area of rectangle = 100 × 52 = 5200 m²
A semicircle is half of a circle
The formula for determining the area of a semicircle is
Area = 1/2 × πr²
Diameter = 52 m
Radius = diameter/2 = 52/2
Radius = 26 m
The area of each semicircle is
1/2 × 3.14 × 26² = 1061.32 m²
The area of the surface of the pool is
1061.32 + 1061.32 + 5200 = 7322.64 m²
Answer:18
Step-by-step explanation:6+8+4 =
18
Answer:
-4
Step-by-step explanation:
(1,-19) (-2, -7)
-19-(-7) = -12 -12 ÷ 3 = -4
1-(-2) = 3
Using the formula:
S = r∅, where S will be the diameter of the moon, be the distance from the earth and ∅ be the subtended angle in radians.
∅ = 3500/400,000
∅ = 8.75 x 10⁻³ radians
