((I've used 3.14 as pi))

Diameter = circumference / pi
= 4.5 / 3.14
= 1.43

Radius = diameter / 2
= 1.43 / 2
= 0.72

V = pi * r^2 * h
= 3.14 * 0.72^2 * 13
= 21.17
= B

astra-53 [7]

Answer:

A) A and B are supplementary

Step-by-step explanation:

we know that

For any inscribed quadrilateral in the circle , opposite angles will be supplementary

In this problem

Angle A and Angle B are supplementary angles

$m\angle A+m\angle C=180^o$

Angle B and Angle D are supplementary angles

$m\angle B+m\angle D=180^o$

therefore

A plane flies an average of 325 miles per hour for 7 hours. how many miles was the flight?

irakobra [83]

If a plane flies an average of 325 miles per hour, to find out 7 hours you will need to times 325 by 7.
325 x 7 = 2275.
therefore the flight for 7 hours was 2275 miles.
