Four circles, each with a radius of 2 inches, are removed
from a square. what is the remaining area of the square?
(16 - 47t) in.?
(16 – ) in.
(64 - 167t) in.?
(64 - 4tt) in.?

Step-by-step explanation:

Given:

radius = 2 in.

Since 4 circles are circumscribed by a square, then the side length of the square is 8

Area of Square =

Area of 1 circle =

Area of 4 circles = 4 × Area of 1 Circle =

According to the question, these four circle are removed by the above square.

Therefore, Remaining Area of the square after removing these four circle= Area of the square- area of 4 circles =

Hence Area of remaining square is

answer: sorry i can't you.

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
