Answer:

A

Step-by-step explanation:

You divide the diameter by 2 to get radius. So 5÷2=2.5

Answer:

84 Percentage increase

Step-by-step explanation:

Detailed calculations & verification

Introduction. Percent, p%

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

40% = 40/100 = 40 ÷ 100 = 0.4.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by 40% of its value.

Percentage increase = 40% × 210

New value = 210 + Percentage increase

Calculate the New Value

New value =

210 + Percentage increase =

210 + (40% × 210) =

210 + 40% × 210 =

(1 + 40%) × 210 =

(100% + 40%) × 210 =

140% × 210 =

140 ÷ 100 × 210 =

140 × 210 ÷ 100 =

29,400 ÷ 100 =

294

Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 210 =

294 - 210 =

84
