Area of a Sector | Worksheet #1

Jog the child's memory and let them recall that the area of a sector is (Θ/360) x πr². All it takes to find the area of the shaded region is to substitute the given measures. A free introductory resource that'll leave children craving for more practice!

Area of a Sector | Worksheet #2

Using the given r (radius) and Θ (central angle), high school learners must obtain the area of a portion of a circle enclosed by two radii and an arc. Let them round the answer to two decimal places so they'll sail through the challenge set here.

Finding Area of the Sector from Arc Length | Worksheet #1

How easy it is to find the area of a sector given the arc length? Remember, only when the steps are followed correctly can this be done right. The key is to find the missing radius or central angle first and then advance toward finding the area of the sector.

Finding Area of the Sector from Arc Length | Worksheet #2

To calculate the sector’s area from arc length, consider the formula arc length = rΘ. Plug in the known values to find the missing r or Θ and proceed to calculate the area of sectors as usual. Follow these steps unerringly at all times so you do well.

Missing Parameters | Worksheet #1

In this section of our pdf area of a sector worksheets, high school students will have two measures. They must determine the unknown parameter – the radius, the central angle, or the area of the sector of a circle accurately.

Missing Parameters | Worksheet #2

Check how correctly the aspirational young learners can calculate the missing measures of the sectors in this printable. Cheer the blossoming mathematicians as they work out the values for r, Θ, or sector’s area using the given values.
