πAnswer:
Therefore, the area of a sector of a circle would be 13.5π square units.
Step-by-step explanation:
Given
The area of a sector of a circle is:
A = π r² Ф/360
A = π (9)² 60/360
A = π 81 * 1/6
A = 13.5π square units
Therefore, the area of a sector of a circle would be 13.5π square units.
Answer:
The equivalent to one over five m − 20 is one over five (m − 100) ⇒ B
Step-by-step explanation:
Let us solve the question
∵ One over five means
∴ One over five m - 20 = m - 20
→ By using the distributive property, take one over five as a common factor
from both terms
∴ m - 20 =
-
→ Simplify the bracket
∵ m ÷
=
m × 5 = m
∵ 20 ÷ = 20 × 5 = 100
∴
-
=
(m - 100)
∴ m - 20 =
(m - 100)
The equivalent to one over five m − 20 is one over five (m − 100)
