How to find the area of 2 half circles and a rectangle
gladu [14]
Hello!

We use different formulas to calculate the areas of different shape.

RECTANGLE:

To find the area of a rectangle, we must simply multiply its length by its width. The formula for its area is:

A = l × w

SEMICIRCLE:

Since the formula for a circle is pi × r × r, we must use the same formula but divide it in half, because a semicircle is a half circle, which is why its area would also be half of a circle's. The formula for a semicircle's area is:

A = 1/2 pi × r × r

Tip:

Write these formulas down and memorize them so that you don't forget them. You'll have to use these formulas quite often when finding the area of these shapes.

PLEASE HELP IM STRUGGLING here is a rectangle all the measurements are in centimeters
scoundrel [369]

Answer:

Area of the rectangle = 95 cm²

Step-by-step explanation:

Perimeter of the rectangle = Sum of the measures of the sides of the rectangle

From the figure attached,

Perimeter of the rectangle = 2[(3x -1) + (2x + 3)]

                                       39 = 2(5x + 2)

                                       39 = 10x + 4

                                      10x = 39 - 4

                                      10x = 35

                                          x = 3.5

Therefore, measure of the given sides will be,

Length = (3x - 1) cm

3x - 1 = (3×3.5) - 1

        = 10.5 - 1

        = 9.5 cm

Width = (2x + 3) cm

2x + 3 = (2×3.5) + 3

          = 7 + 3

          = 10 cm

Area of the rectangle = Length × width

                                   = 9.5 × 10

                                   = 95 cm²

Therefore, area of the rectangle is 95 cm².

A new soup recipe contains 33\%33% less sodium per serving than the old soup recipe. The old soup recipe contained xx milligrams
Eddi Din [679]

Answer: x(1-0.33) or 0.67 x

Step-by-step explanation:

The old soup recipe contained sodium per serving = x mg

According to the question,

The new soup recipe contains 33% less sodium per serving than the old soup recipe.

That is, the Sodium per serving in the new soup = the Sodium per serving in the new soup - 33% of the Sodium per serving in the new soup

= x - 33% of x

= x - 0.33 x      ( since 1% = 0.01 ⇒ 33 % = 0.33 )

= x(1-0.33)

= x(0.67)
