87.3
C=2πR ---} 2×43.668 ---} 87.336
I would say the correct answer is D.
It corresponds with the statement made in the question, saying that 95%(the majority) of customers who rated the store as having high quality service returned.
Don’t get the assignment, rewrite it! If 2/3 of 30km is 20km
Answer:
= 4(1+sin2theta)²
Step-by-step explanation:
Given the equations
tantheta -cottheta =a... 1
costheta +sintheta =b .... 2
We are to find 4b^2(2-b^2)
Squaring both sides of equation 2
(costheta +sintheta)^2 = b^2
cos^2theta + 2costheta sintheta + sin^2 theta = b^2
(cos^2theta+ sin^2 theta) + 2costheta sintheta = b^2
1 + 2costheta sintheta = b^2
1 + sin2theta = b^2
substitute
4b^2(2-b^2)
= 4(1+sin2theta)(2-1+sin2theta)
4(1+sin2theta)(1+sin2theta)
= 4(1+sin2theta)²
18
+ 168
This is because the rectangle's area is 168ft. Then you can find the semicircle's area by finding the area of a circle with a radius of 6 and then dividing that by 2.
