Answer:
C 60π cm³
Step-by-step explanation:
1/3 x π x6² x 5
=60π
In order to prove these triangles congruent by SAS, AB and DE must be congruent. Thus, C is your answer.
Have an awesome day! :)
Pythagoras theorem is c^2 = b^2 + a^2
so when you plug in the numbers its 12^2 + 5^2 =169
which means 144+24=169
square root 169 = 13
AB =13 cm
hope this helps I tried my best. xx
X+2.6=1.7
x+12=7
x+12-12=7-12 (subtract 12 from both sides)
x=-5
Answer:
5√202
Step-by-step explanation:
By Pythagoras theorem,
x^2 = 45^2 + 55^2
= 2025 + 3025
x^2 = 5050
x = 5√202
