Step-by-step explanation:
the total area of circles =
(2 × π × 1²) + (3 × π × 0.5²)
= (2π) + ( 3× 0.25×π)
= 2π + 0.75π
= 2.75π
assume π=3.14
so, the total area =
2.75 × 3.14 = 8.635

Answer:
224
Step-by-step explanation:
a = (bxh)/2
a = (28x16)/2
a = 448/2
a = 224
Answer:
Step-by-step explanation:
given curve y= x^2-4x+3
differentiate wrt x to get gradient,
dy/dx = 2x-4
2a-4= -1
a= 3/2
