Well, a y-intercept is a the point on a graph where the x value equals 0, because the point sits exactly on the y-axis. In this case, the y-intercept would be (0, -9).

What is the area of the beach ball with a diameter of 14 in. ?

Juliette [100K]

Answer:

The answer is 675.75 square Inches

Step-by-step explanation:

<h3><u>Given</u>;</h3>

Diameter (d) = 14 in.

Area of beach ball = ?

<h3><u>Formula</u>;</h3>

Area = 4πr²

Now,

Radius (r) = diameter ÷ 2

r = 14/2 in.

r = 7 in.

Now,

A = 4πr²

A = 4 × 22/7 × (7)² in.

A = 4 × 22 × 7 in.

A = 615.75 square in.

Thus, The area of the beach ball with a diameter of 14 in. is 615.75 square in.

The circular opening of a vase has an inside diameter of 13.5 cm.

Sunny_sXe [5.5K]

Answer:

$Area = 143cm^2$

Step-by-step explanation:

Given

Shape: Opening of a circular vase

$Diameter =13.5cm$

$\pi = 3.14$

Required

Determine the area

This opening implies a circle; hence the area will be calculated using area of a circle.

$Area = \pi r^2$

Solve for radius (r)

$r = \frac{d}{2}$

$r = \frac{13.5\ cm}{2}$

$r = 6.75\ cm$

Substitute 6.75 for r in $Area = \pi r^2$

$Area = 3.14 * 6.75^2$

$Area = 143.06625$

$Area = 143cm^2$ --- Approximated
