7- B
8- C
I’m pretty sure please don’t hurt me if I’m wrong
Answer:
use formula
area =1/4*π*d^2
81π=1/4*π*d^2(here two pie gets cancel)
81=1/4*d^2
81*4=d^2
=d
18=d
Step-by-step explanation:
Answer:
So the answer is the OA :P
Step-by-step explanation:
This means that when the force is applied on a body and the displacement of the body takes place in the direction of the force applied then work done is maximum. So when theta=0°, work done is maximum. !

13 + 15 + 18 +14 = 60 total hats
15 are white
60-15 = 45 hats that are not white
45/60 reduces to 3/4
3/4 =0.75 probability the hat will not be white
Answer:
Step-by-step explanation:
r = 7 cm
h = 15cm
pi = 3.14
Top and bottom (These questions drive you crazy when you don't know if there is both a top and bottom).
Area = 2* pi *r^2 = 2 * 3.14 * 7^2
Area = 2 * 3.14 * 49
Area = 307.72 Don't round this.
Cylinder body
Cylinder body = Circumference * h = 2*pi * r * h
Cylinder body = 2* 3.14 * 7 * 15
Cylinder body = <u> 659.4</u>
