Answer:
20.38
Step-by-step explanation:
64/3.14=20.38
20.38 is the diameter
Answer:
m = 10
Step-by-step explanation:
The triangles are similar. The scale factor is 15/9.
We multiply 6 by the scale factor and get m:
m = 6 * 15/9 = 10
Then we see that m (10) is also the lenght of a side in the smaller triangle, so we multiply 10 by 15/9 and find a.
a = 16,6 (circa)
here is what I think since 2 multiplied by 15 equals 30 you at 35 more to that 30 and you get the answer 60. Is that how it is supposed to go?
Surface Area= Length × hypotenuse+ length × width+2(1/2 base × height)+Lenght×base
Surface Area= 19×25+19×7+24×7+19×24
SA=1232 m²
