Area formula

Dera la ellipse (S) ndi lofanana ndi kutalika kwa ma semiax ake ndi nambala. π:

S = π *a*b

Zindikirani: powerengera mtengo wa nambala π kuzungulira mpaka 3,14.

Chitsanzo cha vuto

Pezani dera la ellipse ngati semiax yake ndi 2 cm ndi 4 cm.

Kusankha:

Timalowetsa zomwe tikudziwa molingana ndi momwe vutolo lilili: S u3,14d 2 * 4 cm * 25,12 cm uXNUMXd XNUMX cm².
