One new school question and answer enquired students to say what they admit is the most crucial important challenge for a student to do to be able to hit success. A lot of responses, one which that stood out was practice. Successful persons surely are not born successful; they become successful with hard work and commitment. This is how you can fulfill your goals. just below are one of the answer and question example that you could potentially implement to practice and expand your understanding and also give you insights that will guide you to preserve your study in school.

## Question:

In a circle, a 90 degree sector has area of 36pi ftsqd. what is the radius of the circle?

## Answer:

The **radius **of the circle is 12 ft.

**Quarter circle**

Each quarter of a circle is formed when a circle is split into four equal sections. Each quarter of the circle is referred to as a **quadrant**. As a result, the area of a quarter circle equals **four times** the circle’s area.

Area = π×r²/4

Where, r is the radius of the circle.

**How to find the radius?**

A **90° sector **of a circle is called a **quarter circle**.

The **area** given in this sector is 36π ft².

then,

Hence the **radius **is 12 ft.
