Question

plz anybody answer this three questions ​

Answer 1

Answer:

8.Radius=diameter/2

=70/2

=35

$circumference = 2\pi \times radius$

= 2×22/7×35

=2×22×5

=44×5

=220 cm

9.Area of triangle = 1/2×base×height

10.3¹⁰÷3⁷

=3 To the power 10 - 7

=3³

=9

Answer 2

QUESTION 8)

☁️|||_ANSWER_|||☁️

⇝ The Circumference Of The Circle is 220cm.

 ⠀ ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

☁️ STEP - BY - STEP EXPLANATION ☁️

☁️ Given:-

• Diameter of the circle = 70cm.

 ⠀ ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

☁️ To Find:-

• The circumference of the circle.⭕

 ⠀ ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

☁️ Solution:-

First we need to find the radius of the circle to find the circumference of the circle.

The radius of the circle:-

Let the radius be r. Then,

r = (Diameter÷2) units.

r = (70÷2)cm

r = 35cm

☁️ Now, the circumference of the circle:-

Formula Applied:-

⇝(2πr) units.

After Substituting The Values:-

⇝(2×22/7×35)cm

⇝ (2×22×5)cm

⇝ 220cm

 ⠀ ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

∴ Hence, The Circumference Of The Circle is 220cm. ✔
