Step-by-step explanation:
step 1
Find the surface area of one hanging lantern
we know that
The surface area of a cone (hanging lantern) is equal to
we have
assume
substitute the values
step 2
Find the surface area of the three hanging lanterns
Step-by-step explanation:
x = speed of hiker1
because they meet, between the 2 of them, together they cover 15 miles in 2 hours.
2×x + 2×(x + 2.7) = 15
2x + 2x + 5.4 = 15
4x = 9.6
x = 2.4 mph
so one hiker was going 2.4 mph,
the other 2.4 + 2.7 = 5.1 mph.
25.3 is the answer to your problem
Divide the figure into a triangle on the left and a rectangle on the right. You know the side lengths of the rectangle are 3 x 10, so multiply to get the area of the rectangle. Next, find the area of the triangle. The area of a triangle is given by 1/2bh, where b is the base and h is the height. Because you know the short side of the rectangle is 3, subtract 3 from 5 to get the base of the triangle. then multiply that by 10, the height, and divide by 2 to get the area of the triangle. Then just add up the area of the triangle and the area of the rectangle to get your answer :)
