## What is the area of a 8cm quarter circle?

Work out the area of this quadrant (radius 8cm). = 64π (leave the answer as an exact solution as this need to be divided by 4). So all you need to do now is divide the answer by 4: Area of a quadrant = 64π ÷4 = 16π = 50.3 cm² to 3 significant figures.

## What’s the area of the radius is 8?

We know that, the Area of the circle with radius r is: A=πr2,where,r=8 inches given. So, A=π(8)2=64π square inches.

**What’s the area of 8cm?**

If 8cm is the length of one side we simply don’t have to perform the first step demonstrated above. We can go right ahead and square the length of the side to get the area of one side of the cube, which is 8 x 8 = 64.

### What is the area of a semi circle?

Area of a Semicircle In the case of a circle, the formula for area, A, is A = pi * r^2, where r is the circle’s radius. Since we know that a semicircle is half of a circle, we can simply divide that equation by two to calculate the area of a semicircle. So, the formula for the area of a semicircle is A = pi * r^2/2.

### What shape is a quarter circle?

A sector can be any size, however a sector that is half a circle (180°) is called a semicircle, while a quarter circle sector (90°) is called a quadrant. A segment is the curved part of a sector, the part that is left if you remove the triangle from a sector.

**What is 1/8th of a circle?**

What is Circle 1/8 Unit of Measure? Circle of 1/8 is a unit of angular measurement. It is also known as octant. A circle of 1/8 is equal to 45 degrees.

#### What is the diameter of 8cm?

Circle with diameter 8cm. Circumference = π × 8cm = 25.1cm to 1 decimal place. Circle with diameter 16.5cm.

#### What is the area of the semi circle whose radius is 8cm?

We can confirm this using the formula for area of a semi-circle, A=r2π2 .

**What is the area of a circle with radius 8?**

The area of a circle with radius 8 is 201.1.

## How do you find the area of a quarter of a circle?

How to Find the Area of a Quadrant (a Quarter of a Circle) A quadrant is a quarter of a circle. So to work out the area of a quadrant, first work out the area of the whole circle (use the formula A = π ×r²) and then divide the answer by 4. Alternatively, you could substitute the radius of the quadrant directly into the formula A = ¼ πr².

## What is the area of the circle with diameter 16?

Result in other units of area: A circle of radius = 8 or diameter = 16 or circumference = 50.27 cm has an area of: 2.011 × 10 -8 square kilometers (km²) 0.02011 square meters (m²)

**How do you work out the area of an 8cm quadrant?**

Work out the area of this quadrant (radius 8cm). Method 1 (using the area of a whole circle and dividing by 4) First work out the area of the whole circle by substituting the radius of 8cm into the formula for the area of the circle: A = π ×r². = π ×8². = 64π (leave the answer as an exact solution as this need to be divided by 4).
