40
Step-by-step explanation:
6x7-8/4 =42 - 2 = 40
Answer:
10.5 squared centimetres.
Step-by-step explanation:
First, find the area of that sector. We are already given that the circle is 154 squared centimetres.
We are given 90 degrees (or one fourth of the circle). Thus, divide 154 by 4 to get the area of the sector (the white area).
The area of the sector is 154/4 or 38.5
We then need to find the area of the square. After that, we can subtract the sector area (the white area) from the area of the square (the total area) to find the area of the shaded section.
The area of the square is 7*7 or 49.
Thus, the shaded portion will be 49-38.5 or 10.5 squared centimetres.
Answer:
648 inches squared or 54 feet squared
Step-by-step explanation:
12*9=108
108*6=648
684/12=54
Answer:
Step-by-step explanation:
<u>Using the the equation </u>
<u>The ball hits the ground, when h = 0, solving below equation:</u>
- 100t − 16t^2 = 0
- 4t(25 - 4t) = 0
- t = 0 seconds, this is the starting point when ball was hit
- 25 - 4t = 0 ⇒ 4t = 25 ⇒ t= 25/4 = 6.25 seconds later the ball hits the ground
