Hi hopefully this helps you!
Step-by-step explanation:
To find the area of a circle you can use the formula A = πr^2
The radius of a circle is just the diameter divided by 2. In this case we know the diameter is 3, so the radius is 1.5
A = π(1.5)^2
= 7.07
Because this is a semicircle, divide this area by 2
= 3.53429 in^2
Add up the area of this semi circle with the area of the rectangle
A = (3.53429) + (3x4)
= 15.53429 in^2
To find the circumference/ perimeter of a circle use this formula C = 2πR
C = 2π(1.5)
= 9.42478 inches
Again because this is a semicircle, divide by 2
= 9.42478 / 2
= 4.71239 inches
To find the perimeter of this entire shape add up the circumference of the semicircle and the rectangle's sides and bottom
P = 4.71239 + 4 + 4 + 3
= 15.71239 inches
So the final answer would be
A = 15.53 squared inches
P = 15.71 inches

Answer:
c=24
Step-by-step explanation:
c/3 = 8
Multiply each side by 3
c/3 *3 = 8*3
c=24
Step-by-step explanation:
From the question
Perimeter = 2L + 2W
L = 24 units
W = 11 units
Substitute the values into the above formula
That's
P = 2(24) + 2(11)
P = 48 + 22
P = 70 units
Therefore the perimeter of the rectangle cannot be 60 units since the values when substituted into the above formula will give us 70 units
Hope this helps you

First find the LCM which is 6 so multiply 
by 3 to get 
and multiply 
by 2 to get 
and then add 
I can try to explain how to get LCM if you don't know how
I'm bad at explaining things but I tried :/
