Question

find the area. use 3.14 or a calculator button for pi and provide an answer accurate to the nearest tenth. 6 mm label required

Explanation:

Step1: Identify shape and formula

The shape is a quarter-circle (90° sector, 1/4 of full circle). Area formula: $A = \frac{1}{4} \pi r^2$

Step2: Substitute radius $r=6$ mm

$A = \frac{1}{4} \times 3.14 \times 6^2$

Step3: Calculate step-by-step

First compute $6^2 = 36$, then $\frac{1}{4} \times 36 = 9$, finally $9 \times 3.14 = 28.26$

Step4: Round to nearest tenth

$28.26 \approx 28.3$

Answer:

28.3 mm²
