Maria and Tram want to build a dirt bike ramp. They know the dimensions of the base (350 cm) and the height (25 cm), but they need to know the angles to decide how to cut the wood accurately. Maria made a scale drawing and used it to estimate that the slope angle (`x`) is about 4 degrees. Tram thinks the angle is about 10 degrees. But Tram thinks there must be a way of using the calculator to get the slope angle.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

110698.56 square miles

step-by-step explanation:

multiply 3.8 by 102

387.6

multiply 2.8 by 102

285.6

multiply those two to get
