Question

HI MATHS EXPERTS PLS ANSWER ASAP PLS I AM DESPERATE

Answer 1

c. 2310 (1st pic)

circumference of circle = 2πr

44= 2 × 22/7 r

44 × 7 / (2 × 22) = r

7 = r

volume of cylinder = πr^2h

= 22/7 × (7)^2 ×15

= 2310

b. -2/x+3 (2nd pic)

(work attached)

a. 80° (3rd pic)

Total number of degrees is 180

180-(60+40)=80

c. 9 (5th pic)

(27^1/3)^2

3^2

=9

sorry i couldn't solve the 4th pic but I hope this helps!

please mark me brainliest!
