Step-by-step explanation:
Answer: h= -2.5t + 15
Step-by-step explanation:
If it is burning at a constant rate it means that the height is decreasing so the slope which is 2.5 cm per hour has to be negative.
(2 + 8) / 2 * 9 / 3
Using order of operations, you will solve what is in the parenthesis first.
10 / 2 * 9 / 3
Then you divide.
5 * 3
Then you multiply.
5 * 3 = 15
Hope this helps!
Answer:
The Area of shaded portion is 314000 cm²
Step-by-step explanation:
Given as :
The circle is drawn with radius = r = 10 cm
Two portion of circle is shaded
∵ two portion is shaded means whole the circle is shaded now
Let The area of shaded portion = A = area of circle
∵ Area of circle = A = π × radius²
where π = 3.14
Or, A = 3.14 × r²
Or, A = 3.14 × (100)²
Or, A = 3.14 × 10000
Or, A = 
I.e A = 314000 cm²
So, The Area of shaded portion = A = 314000 cm²
Hence, The Area of shaded portion is 314000 cm² Answer
