your answer is c 29. To figure this out take 59-180= 121. Then add 121 and 30 =151. next subtract 151 from 180 and you get C 29
Answer:
361.7cm²
Step-by-step explanation:
Volume of sphere 1= 8cm³
=
Volume of sphere 2 = 647cm³
But volume of sphere = 4/3πr³
The radius of sphere 2
647 = 4/3πr³
((3*647)/4)/π= r³
5.36544 = r
Surface area = 4πr²
Surface area for the big sphere
= 4π5.36544²
= 361.7cm²
Step-by-step explanation:
radius(CE)=diameter/2=9
EF=8inch
DE=8/2=4inch
pythagorean theorem:
im right triangle,
a^2+b^2=c^2
4^2+b^2=9^2
16+b^2=81
b^2=81-16
b^2=65
b=√65
√65≈8.06
You would have to multiply 37 by 15
37 x 15 = 555
Answer:
74°
Step-by-step explanation:
From the attached figure, translation only affects the length of the sides of the triangle :
From the figure :
We are given ;
A = 80° ; C = 26° ; B =?
Sum of angles in a triangle :
A + B + C = 180°
80° + B + 26° = 180°
106° + B = 180°
B = 180 - 106
B = 74°
