Answer:

210.25 or 210.3495409 depending on how your teacher does it

Step-by-step explanation:

Looking for circumference of the circle when it asks for perimeter

Formula for Circumference C = π x r <em>3 (cubed)</em>

The diameter is 10 so you take half of ten or 10 ÷ 2 = 5

5 x 5 x 5 = 125 (r squared equation)

125 x π = 392.6990817

Some classes ans stuff use 3.14 for pi so i'll show it that way too

125 x 3.14 = 392.5

(equation with π)

392.6990817 ÷ 2 = 196.3495409

196.3495409 + 14 = 210.3495409

(equation with 3.14)

392.5 ÷ 2 = 196.25

14 + 196.25 = 210.25

Anestetic [448]

Answer: See explanation

Step-by-step explanation:

Number of children on museum trip = 20/100 × 369

= 1/5 × 369

= 73.8 = 74 approximately

Number of children in school = 369 - 73.8 = 295.2 = 295 approximately
