Answer 1

Answer:

answer of question 8

radius = 2.8 / 2 = 1.4 cm

circumference of circle is 2πr

= 2 × 22/7 × 1.4

= 8.8 cm

question 9

area of tri is 1/2 × base × height

= 1/2 × 18 × 6.2

= 55.8 cm²

question 10

radius = 16 cm

Area of circle is πr²

= 3.14× 16 × 16

= 803.84 cm²

Answer 2

Step-by-step explanation:

7:-

Area of the parallelogram = Base×Height = 6.1×3.6 = 21.96 cm².

8:-

Diameter = 2.8 cm

Radius = Diameter/2 = 2.8/2 = 1.4 cm = 14/10 cm

Circumference of the circle = 2πr = 2× 22/7 × 14/10 = 8.792 cm.

9:-

Area of the triangle = 1/2 × Base × Height = 1/2 × 18×6.2 = 55.8 cm².

10:-

Area of the circle = πr² = 22/7 × 16 × 16 = 804.57 cm².
