A helicopter's rotor sweeps out an area of 121 pi square
Nuetrik [128]

Answer:

<h2>22 meters.</h2>

Step-by-step explanation:

It's important to notice that the area is circular, which is defined by

A= \pi r^{2}

Replacing given values and solving for r, we have

121 \pi = \ pi r^{2} \\121=r^{2}\\ r= \sqrt{121}=11

But, the diameter is twice the radius, so

d=2r=2(11)=22

Therefore, the diameter is 22 meters.

PQRS is a parallelogram and T is the mid point of PQ if ar PTRS=24 cm^2, find the area of PQR​
Lady_Fox [76]

Answer:

24 sq cm

Step-by-step explanation:

According to theorem of area if parallelogram and triangle, if the triangle and a parallelogram lie between two parallel line and their base is same then, the area of triangle is half of the area of the parallelogram. so here the parallelogram PTRS and the triangle PTR lie between same parallel lines PT and RS and base is also same PT. so area of PTR is 12sq cm. Again, triangles PTR and TRQ lie between same parallel lines PQ and SR and same base PQ. so their area also same that is 12 sq cm. Now, area of PQR = area of PTR + area of TRQ = 12 + 12 sq cm = 24 sq cm.
