Answer:
69.1 cm
Step-by-step explanation:
Circumference of a circle
c = 2πr
Half of that would be a semi-circle
c = πr
c = π * 22
c = 69.115038379
Rounded
69.1 cm
The answer is 76.99 but rounded would make it 77.00 which is C
X= a number
If 52 is 130% of a number, then we multiply the unknown number by 130%.
x * 130%= 52
convert % to decimal (130%÷100)
1.3x= 52
divide both sides by 1.3
x= 40
ANSWER: The unknown number is 40, so it is less than 52. We multiply the unknown number by 130% to equal 52.
Hope this helps! :)
answer is 1.566 deg
Step-by-step explanation:
The angle of elevation is given by the formula
tanθ = height/distance
tanθ = H/ 240
tanθ × 240 = H
θ =( tan∧-1) 240
= <u>1.566 deg</u>
