Answer:

Area of circle, A = 616 cm^2

Step-by-step explanation:

Area of circle:

A = πr^2

Given: d = 28 cm and π = 22/7

so r = d/2 = 28/2 = 14 cm

So

A = π r^2

A = 22/7 * 14^2

A = 22/7 * 196

A = 616 cm^2

So 14*2=196

196π equals to 615.75

I think it’s 104,974
Because PEMDAS,
so first deal with exponents and 3 to the fourth power is 81. 6 to the fourth power is 1,296.
Next in PEMDAS is multiplication and division, so 1,296 times 81 is 104,976. Then 4 divided by 2 is 2.
Finally comes subtraction, 104,976 minus 2 = 104,974
