In the following questions, the radius of circle O is given, as well as the measure of central angle AOB. Find the area of the segment of circle O bounded by AB and AB . Give exact values whenever possible. Otherwise, round answers to the nearest hundredth. Radius: 7 inCentral Angle: 4π/5A. 370.4 in2
B. 81.4 in2
C. 47.2 in2
D. 32.8 in2
E. 320.8 in2
F. None of these

C.47.2 square in

Step-by-step explanation:

We are given that

Radius,r=7 in

Central angle,rad

We have to find the area of segment of circle O.

Area of segment=Area of sector-Area of triangle

Area of triangle=

Area of sector=

Area of segment=(61.57-14.4)square in

Area of segment=47.17 square in

Hence, option C is true.

the answer is b

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04
