4 2/3
Step-by-step explanation:
Answer:
r=√(A/π)
r=2.8
Step-by-step explanation:
We want to get (r) alone on one side
A=πr^2
divide each side by π
A/π=r^2
square root each side
√(A/π)=r
r=√(A/π) is the answer to your first question.
now we are given A
r=√((25)/3.14)
put the left side into a calculator
r=2.8216632
round to nearest tenth of a centimeter
r=2.8
The answer would be 29 because 9 + 36 = 45 - 16 equals 28
D) 16 m2
The area of the larger square is 8 x 8 = 64. The smaller is 4 x 4 = 16.
The unshaded portion is 64-48=16
