Answer:
shape AREA= 35cm^2
Step-by-step explanation:
you should know that this shape is a combination of triangle and trapezoid. therefore you have to find the area of each shape and add them.
A=h/2(b1 + b2) for trapezoid
A=2/2((4+4)+4)
A=1*12
A=12cm^2
A=bh/2. for TRIANGLE
A=1/2((4+4)*5.75)
A=1/2(46)
A=23cm^2
shape AREA= triangle AREA + trapezoid AREA
shape AREA=12cm^2 + 23cm^2
shape AREA= 35cm^2
Answer:
12
Step-by-step explanation:
HOPE IT HELPS!!!!!!
I find it easier to have a visual for when solving for shapes. You should solve for area of the semicircles by doing A=(3.14r^2)/2
Radius in this case is the base /2
In a Calculator that can be inputted as (3.14(4))/2
for this problem though I'm afraid that I need to know whether the height belongs to the figure as a whole or just regarding the rectangle.
If it is just the rectangle then we can do A=B*h
A= 4*5= 20
20 + semicircle
20 + 6.28
Total= 26.28
Answer:
He had $22.60
Step-by-step explanation:
$9.50 + $4.35 = 13.85 + 8.75 = $22.60
Answer:
Time at which the hammer reaches the ground is 2.3 seconds.
Step-by-step explanation:
We are given the formula as, 
.
It is known that, when height i.e. 
meter, then velocity 
m/sec.
So, we get the formula as, 
.
Now, when the hammer hits the ground, the height 
meter.
Thus, we have,
⇒ 
⇒ 
⇒ 
i.e. t= ±2.3 sec
Since, time cannot be negative.
So, t= 2.3 sec
Hence, the time at which the hammer reaches the ground is 2.3 seconds.
