Question

if the circumference of a circle is 352 cm then find the radius and area of the circle​

Answer 1

Answer:

r = 56 cm

area = 9856 cm^2

Step-by-step explanation:

Radius

Circumference of a circle = 2 π r

Circumference of a circle = 352 cm

• 2 π r = 352
• 2×(22/7)×r = 352
• r = 352×7÷(2×22)
• r = 176×7÷22
• r = 88×7÷11
• r = 8×7

• r = 56 cm

Area

• area of a circle = πr^2
• area of a circle = 22/7×56×56
• area of a circle = 22×8×56

• area of a circle = 9856 cm^2

Answer 2

Here the circumference of the circle is given to be 352 cm

We have to find the radius and area

We will first find out the radius of the circle by using formula of circumference

circumference = 2πr

352 = 2 × (22/7) × r

r = 56 cm

Now, we will find the area of the circle

area = πr²

= (22/7) × 56 × 56

= 9856 cm²

Hence, the radius and area of the circle will be 56 cm ans 9856 cm²
