The main formula is A= 2pi r (H + r)
H= 9, and r= 11
so A= 2 *3.14*11* (9 + 11) = 1381.6 cm²
so the answer is <span>1380 cm2</span>
Answer:
Step-by-step explanation:
s=18, t=18 the s gives t x sweets
s=18-x, t=18+x, s eats 5 and t eats half
s=18-5-x, t=(18+x)/2
Reamining sweets is
R=s+t
R=18-5-x+(18+x)/2
R=13-x+(18+x)/2
R=(26-2x+18+x)/2
R=(44-x)/2

↪SURFACE AREAS AND VOLUMES
↪The VOLUME of any object is nothing but the the capacity to hold the amount of substance inside it . It defines the Amount of substance that can occupied bythe object inside it ..
↪Volume = Base Area × Height
↪thus for the Cylinder ; Volume of cylinder = Pi(R^2) × H
↪thus volume = 3.14 × R^2 × H
↪thus here given as R = 4 cm and H = 12cm
↪Volume = 3.14 × 16 × 12= 602.88 cm^3
thus
↪the Volume of the Cylinder = 602.88 cm^3
