A. 72 feet because in the triangle 5•4/2 is 17.5. The rectangle 12•4 is 48. The semicircle pi2^2/2 is 6.2. Added together everything is 71.78 which rounded, is 72

Answers:

a) x = 9
b) arc JK = 68
c) arc MJ = 112
d) arc LMK = 248

================================

Explanation:

Arcs JK and KL form a semicircle, so they add to 180 degrees

(arcJK) + (arcKL) = 180

(5x+23) + (17x-41) = 180

22x-18 = 180

22x = 180+18

22x = 198

x = 198/22

x = 9

Then you'll use this x value to find arc JK and arc KL

arc JK = 5x+23 = 5*9+23 = 68

arc KL = 17x - 41 = 17*9-41 = 112

Since central angles MNJ and KNL are vertical angles, this means minor arcs MJ and KL are congruent arcs. So arc MJ is also 112 degrees

Arc LMK is basically nearly everything of the full circle, but we exclude out the portion from L to K (the shorter distance)

arc LMK = (full circle) - (measure of minor arc LK)

arc LMK = 360 - 112

arc LMK = 248

A standard dartboard has a diameter of 18 in. What is its area to the nearest square inch?

Reptile [31]

The meaning of the area is the measurement of a surface in this case a circle, which can be find by using the formula $A= \pi r^{2}$ , where r is equal to the radius of the circle.

In this exercise is given that the diameter of a standard cardboard is 18 inches or a radius of 9 inches and it is asked to find its area. Therefore, to find the area of the circle you should substitute the value of the radius into the previous mention formula.

$A= \pi r^{2}$
$A= \pi (9 in)^{2}$
$A= \pi (81 in^{2})$
$A=254.47 in^{2}$

The area of the standard dartboard is 254.47 square inches or 254 square inches.
