Find the area of the shape below giving your answer to 1 decimal place.

Answers

Answer:

198.5 cm²

Step-by-step explanation:

From the figure above we can treat the two semi circles as 1 circle.

Now, the diameter is 10 cm

Thus;

Radius; r = 10/2

r = 5cm

Now, formula for area of a circle is;

A = πr²

Thus;

Area of 2 semi circles = Area of 1 circle = π × 5²

A_circle = 78.54 ≈ 78.5 cm²

When we take out the 2 semi circles, what we have left is a rectangle.

Now, the length of the rectangle will be;

Length; L = 22 - 5 - 5 = 12 cm

*This is because the radius of the semi circle is 5 and distance from the edge of the 22 cm length to the centre of the semi circle is 5 cm

Thus, area of rectangle is given by;

A_rect = LW

W in the image is 10 cm

Thus;

A_rect = 12 × 10

Total area of shape is;

A_total = 120 + 78.5

A_total = 198.5 cm²

Do these ratios form a proportion 12/16 and 15/20

Answers

Answer:

This is a proportion

Step-by-step explanation:

Cross multiply:

12 * 20 = 16 * 15

Simplifying:

12 * 20 = 16 * 15

Multiply 12 * 20

240 = 16 * 15

Multiply 16 * 15

240 = 240

Add '-240' to each side of the equation.

240 + -240 = 240 + -240

Combine like terms: 240 + -240 = 0

0 = 240 + -240

Combine like terms: 240 + -240 = 0

0 = 0

Solving

0 = 0

Veronica cut a triangular piece of cookie cake with side lengths that measure 3.6 cm, 6 cm and 4.8cm.

Did Veronica cut out a right triangle?

Answers

Answer:3.6 + 4.8 > 6

Step-by-step explanation:

The answer is YES, the triangle that is cut down by Veronica is a right triangle.

What is a triangle?

The basic polygonal shape of a triangle has three sides & three interior angles. This is one of the fundamental shapes in geometry and is particularly associated. It has three connected vertices. Triangles can be divided into a variety of categories according to their sides and angles.

As per the given information in the question,

The lengths of the sides of the triangle are given as,

Let Base, b = 3.6 cm

Perpendicular, p = 4.8 cm

Hypotenuse, h = 6 cm

Now, use the equation of Pythagoras' theorem,

h² = p² + b²

6² = 4.8² + 3.6²

36 = 23.04 + 12.96

36 = 36

It satisfies Pythagoras' theorem, which means that it is a right triangle.
