Answer:
45
Step-by-step explanation:
To know how many 1/5 s are in 9, we will take the ratio of both numbers as shown;
9:1/5
= 9 ÷ 1/5
= 9 * 5/1
= 9 * 5
= 45
Hence there are 45 1/5s in 9

Step-by-step explanation:
The lateral area of the pyramid is 108.49 cm^2. The lateral surface area is the total of all of each side's area of a three-dimensional figure and it has a different method to calculate it. First, you must find the triangle's height by using the Pythagoras formula resulting 7.41 cm ( =squareroot(8^2-3^2)), thus, you can find the lateral area using the square and triangles area formula (108.49=(8*8) + 4*(0.5*3*7.41))<span>.</span>
BA is tangent to circle O to BA perpendicular to OA
given :BA = 15, OB = 17
a^2 = c^2 - b^2
a^2 = 17^2 - 15^2
a^2 = 289 - 225
a^2 = 64
a = 8
OA = OC = 8
answer
radius of circle O = 8
