You said that the radius is 4cm.

We can use the formula for the area of a circle: π x r²

So π x (4)²

is π x 16

= 16π

= 50.3 cm² (aprox).

At school, 588 students bought a school
Reptile [31]

Answer:

80%

Step-by-step explanation:

Step 1: Add the given data

588 + 147 = 735

Step 2: Divide the number of students who bought a school shirt by the total number of students

588 ÷ 735

= \frac{735}{588}

= 0.8

Step 3: Convert the decimal to fraction

0.8 = 80% (Move the zero 1 place behind the number and remove the ".")

Or

0.8 × 100 = 80%

Therefore, 80% of students bought a school shirt.
