Answer:

∠TAR = 35°

Step-by-step explanation:

∠TAR = ∠CAR - ∠CAT = (9x + 7) - 5x = 4x + 7

AT bisect ∠CAR ∠TAR = ∠CAT

4x + 7 = 5x

x = 7

∠TAR = 4 x 7 + 7 = 35

A bicycle wheel with radius 30cm made 1000 revolutions. What distance did it cover?

Inga [223]

The distance covered by bicycle is 1.885 km.

What is distnace?

Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. Distance can refer to a physical length in physics or to an estimate based on other factors in ordinary language.

Given: A bicycle wheel with radius 30cm made 1000 revolutions.

We have to find the total distance covered by bicycle.

First to find the circumference of the bicycle wheel.

Circumference = 2πr

where, r is the radius.

Here r = 30.

So,

Circumference = 2 x π x 30 = 60π

Now to find the total distance,

D = circumference x number of revolutions.

D = 60π x 1000

D = 188,495.5592 cm

D = 188,495.5592 /1000 km

D = 1.88 km

Therefore, the distance covered by bicycle is, 1.885 km.
