The radius is 10.4 cm. And the angle is 120 which is 1/3 of the circle. Just use the area formula: 3.14 *r^2 to find the total area of 339.62 and then divide this by 3 to get 113.21. Then to subtract the triangle..find the area of the traingle which is 1/2 (10.4)^2 = 54.08. 113.21 - 54.08 = 59.13 which should be your answer
A pair of jeans costs $89.A Jean jacket costs twice as much. What is the total cost of a jean jacket and 4 pairs of jeans?
Answers
It is given here that the cost of a pair of jeans is $89. It is also given in the problem that a jeans jacket costs twice as much as the pair of jeans. Now The cost of the jeans jacket = (2 * 89) dollars = 178 dollars Cost of 1 pair of jeans = 89 So The cost of 4 pairs of jeans = (89 * 4) dollars = 356 dollars So we come to know that the cost of a jean jacket is $178 and the cost of 4 pairs of jeans is $356. Total cost for the jean jacket and 4 pairs of jeans = (178 + 356) dollars = 534 dollars So $534 is the total cost of the jean jacket and 4 pair of jeans.
