Answer:
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
Hope this helps! Best of luck in your studies <3
Answer:
80 feet.
Step-by-step explanation:
Given:
The length of a rectangular garden is 10 yards and its width is 10 feet.
To find:
Perimeter of the garden in feet ?
Solution:
Length = 10 yards
1 yard = 3 feet
10 yards = 3
10 = 30 feet
Breadth = 10 feet
Now, as we know:


Hence, the perimeter of the garden is 80 feet.
Answer:
252cm
Step-by-step explanation:
18/2=2
9*14=126
126*2=252

<h3>HERE IS YOUR ANSWER</h3>
TSA OF CONE = πr ( l + r )
= 22/7 * 6/2 cm ( 5 cm + 6/2 cm )
= 22/7 * 3 cm ( 5 cm + 3 cm )
= 22/7 * 3 cm * 8 cm
= 528/7 cm²
