B) Yes, they are both right angles.
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
pi*r²=616
22×r²=616×7
r²=4312/22
r=14
now
2piR=2×22/7×14
=88
By cosine rule, the length of the longer diagonal is sqrt(60^2 + 40^2 - 2 x 60 x 40 cos 132) = sqrt(8,411.83) = 91.7 cm
The other angle of the parallelogram is 180 - 132 = 48
The length of the shorter diagonal is sqrt(60^2 + 40^2 - 2 x 60 x 40 cos 48) = sqrt(1,988.17) = 44.6 cm
