I’m having a lot of trouble, can someone guide me, step by step?
shutvik [7]

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

The length of a rectangular garden is 10 yards and its width is 10 feet. What is the perimeter of the garden in feet???? This wa
AVprozaik [17]

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 \times 10 = 30 feet

Breadth = 10 feet

Now, as we know:

Perimeter\ of\ rectangle=2(length+breadth)

                                       =2(30+10)\\ \\ =2(40)\\ \\ =80\ feet

Hence, the perimeter of the garden is 80 feet.
