This is my concluding answer let me know if it's right or wrong please!! the area of a circle is (pi)r2

first let me find what is the radius

4.5 2 = 2.25

2.25 - 1.5 = 0.75

2.25 2.25 which is (3.14) = 15.896

0.750.75 which is (3.14) = 1.76625

and subtract

15.896 - 1.76625 = 14.12975cm^2

Write the equations in logarithmic form 7^3=343

Plzzz answer both questions and i will give you 100 points

Grace is standing 18 feet from a lighthouse and kelly is standing 10 feet from grace. the angle that grace looks up to see the top of the lighthouse is 45°. the angle that kelly looks up to see the top of the lighthouse is y°. find the height, h, of the lighthouse. find the angle, rounded to the nearest tenth of a degree, in which kelly looks up to the top of the lighthouse. to the nearest tenth of a degree, find the value of x° . in two or more sentences, explain your calculations
